CEE Department Head JIM GARRETT reetings from CEE at Carnegie Mellon! I am very pleased to report that we are experiencing robust enrollments at both the undergraduate and graduate levels. Our undergraduate program currently has 117 students spread relatively evenly over the sophomore, junior and senior classes. At the same time, we have enrolled 104 full or part-time graduate students this fall (58 Ph.D. students and 46 M.S. students), making them our largest graduate student body ever.

I am also very pleased to announce that Julia and Michael Ellegood (CE ’60) have generously established the first Strategic Graduate Fellowship in CEE which will be used to help support doctoral students performing early-stage research in strategic areas. We are grateful to the Ellegoods for this important and generous support; details of this fellowship are presented later in this newsletter.

In the past six months, we have also established a number of exciting graduate programs with other international universities. In October, President Cohon signed a memorandum of understanding (MOU) with the Korean Advanced Institute for Science and Technology (KAIST) to establish a dual Ph.D. degree program between our two CEE departments. Students in this program will spend a minimum of 2 years at each university, meet all requirements from both programs, and produce a dissertation that is acceptable to both programs. The program will provide our department with access to students, research opportunities, and resources that may not have been available to us alone. In May, we signed another IN THE PAST SIX MONTHS, WE HAVE MOU with the recently established University of Trinidad and Tobago. UTT was created by the government of Trinidad and Tobago to transition the natural resources ALSO ESTABLISHED A NUMBER OF EXCITING of the country (i.e., natural gas) into more knowledge-based assets. The MOU with UTT establishes a number of different activities, such as educating graduate students GRADUATE PROGRAMS WITH OTHER who will become UTT faculty members, hosting undergraduate and faculty INTERNATIONAL UNIVERSITIES exchanges, and assisting them in the creation of their curriculum. Both of these initiatives will bring new students to our program and allow us to build much deeper relationships with important international partners. We are currently exploring similar relationships with other partners with whom we currently have strong interactions.

We are pleased to announce that at our Alumni Dinner this past fall the Distinguished Alumnus Award was presented to Rex Elder (CE ’40) and the Outstanding Alumni Service Award was presented to Wayne Balta (CE ’82).We offer them both hearty congratulations for these awards!

We’ve expanded our alumni related events and activities. The events planned for 2008 are listed on the back cover of this newsletter and on our website. We invite all CEE alums to join us at these events and welcome your ideas for other alumni activities. I encourage you to bookmark our new website (www.ce.cmu.edu) to keep current of the exciting activity going on in CEE. Thanks to all who help to make CEE at Carnegie Mellon a better place to work and study.

Many, if not most, phenomena in the natural and built environment occur at “macro-scales” which are many, many times coarser than the most elementary scales which govern them: the “micro-scales”. The two examples shown here are the deformation of an automobile frame during a traffic accident and a landslide in saturated soil after heavy rains in southern California. For the deformation of the auto frame, the most fundamental micro-scale objects that govern the response are the atoms which make up the metal in the frame; for the landslide, the most fundamental micro-scale objects are the grains of soil on the hill side. The laws which govern the micro-scale are well-known. One could, in principle, use “brute force” to directly simulate all of the elementary objects at the micro-scale.

However, it will not be possible to perform these simulations in the foreseeable future with even the most powerful computers on the planet: a very rough estimate would give as many as 1024 soil grains in a hill-side and 1028 atoms in an auto-frame; molecular simulations of metals require resolving atomic vibrational time scales of ~10 -15 seconds while the time scale over which the auto frame deforms in rapid impact is ~1 second, a 15 order of magnitude difference.

On the other hand, the materials themselves often point to a more clever kind of modeling which can be done. If one were to look under a microscope, it would become apparent that there are other objects which are intermediate between the micro and macro scales which play an important role. In the case of metal plasticity, there are defects in the crystalline packing called dislocations that one can see here in the Transmission Electron Microscope (TEM) image shown in Figure 1. In the case of the grains, one observes chains of forces which emerge to support the applied loads which one can see in the image of a sheared packing of birefringent plastic beads shown in the middle row of Figure 1 (the color of each plastic bead represents the forces which are transmitted through it). It is the goal of multi-scale modeling of materials to infer the laws that govern the interaction of these objects at the coarser “meso-scales” using tools from continuum mechanics, dynamical systems theory, statistical physics, and the theory of partial differential equations. In our opinion, this type of sequential multi-scale approach is the only hope for being able to model macroscopic phenomena starting from microscopic principles.

Multiscale Modeling for Engineering Materials

Figure 1: Multiple scales involved in macroscopic phenomena of interest

All of the above applications require a fundamental understanding of the mechanisms of stressing and deformation of the involved materials and structures at appropriate length and time scales. An important realization is that it is not possible to acquire the required understanding from experimentation alone, if at all. Even in cases where this may be possible in principle, present-day cost constraints make this solely experimental paradigm impractical; it is simply not possible in today’s day and age to have a decade-or-more long design cycle to introduce a material for a specific application. Thus, advanced physical modeling along with robust numerical simulation of these models is a key to success in the applications described and many others.

At the scale of angstroms and femtoseconds, all of our materials of interest can be described by quite reliable physical theories (molecular dynamics/quantum mechanics) whose solutions, in principle, can be computed at arbitrarily larger length and time scales. However, except for very few applications related to the design of new materials for

Materials, either natural or man-made, are a ubiquitous feature of our built and natural environment. They appear as geologic media through which our evolving planet interacts with us, as load-bearing structural members, as machine parts and as microelectrical mechanical systems (MEMS) in the devices used to sense our environments. Understanding the mechanics of materials is important for many reasons: 1) mitigating the damage due to natural disasters, such as earthquakes, by predicting likely areas to see damage and thus providing early warning; 2) to aid in the design of more earthquake resistant structures and materials; 3) for avoiding catastrophic land-slides due to failure and rapid flow of granular media like saturated soils; 4) for better and more cost-effective design with existing materials used in structural, energy, and sensing applications, such as NiAl and TiAl alloys for light-weight, high-temperature operation in turbine engines for energy needs; and 5) for the design of new materials providing targeted functionality, such as highstrength and high-ductility, as in bulk metallic glasses or advanced high strength steels.

dislocation. Examples of such structures are semiconductor thin films used in electronic devices (LEDs, transistors), and metallic interconnects in integrated circuitry and actuators in MEMS devices. It is well known that deformation microstructures in structural metals critically affect their response to loads – such microstructures are also the result of plasticity in the lengthscale range mentioned above. The goal of Professor Acharya’s research in Field Dislocation Mechanics and its appropriate averaging is the understanding of single and polycrystalline plasticity from the nano to macro scales, with a view towards Figure 2: Dislocation microstructure and size effect in stress-strain response for micron scale metal plasticity developing predictive theory and computational tools for deformananoscale applications, all of the applications of our interest occur at tion-induced microstructure evolution.

Professor Maloney performs computer simulations of these metallic glasses at the level of individual atoms. Figure 3 shows a simulation containing a 2 dimensional slice of 1.6 million atoms. Simulations like these take several days of dedicated time on a cluster of more than 100 CPUs. The sample is being compressed vertically, and the color represents horizontal displacement in a short window of time. Shear strain appears as a sharp gradient in color. The width of the bands that emerge in the simulations is only a few atomic spacings, while the ones observed in the laboratory are thousands of times wider. However, the atomic scale bands seen in the computer simulations form in a correlated way, with new bands forming preferentially near existing ones. Prof. Maloney is currently working with Prof. Acharya to develop meso-scale descriptions, within the Field Dislocation Mechanics framework, using the atomic scale simulations to parameterize the meso-scale models.

Figure 4: A ferroelectric crystal under electromechanical loading undergoes complex microstructural changes

Understanding Active Materials Active materials display unusual couplings between deformation, temperature, optics, and electromagnetism. Current research and development of micro-nano electromechanical systems (MEMS/NEMS) provides new opportunities for exploiting these unusual materials. These opportunities also require a fundamental understanding of the behavior of active materials at these small scales, especially in dynamic settings.

Professor Dayal’s research aims at formulating mesoscopic models and developing numerical techniques to aid design and fabrication of active nanoscale devices. Currently, he focuses on using ferroelectrics to design new optical switching devices and microwave circuit elements. A parallel study aims at an atomic-level understanding of instability, nucleation, and kinetics of microstructural elements in active materials. This will enable development of atomistically-informed mesoscopic models, and provide multiscale capabilities to understand and exploit these complex materials.

In the figure 4, a ferroelectric specimen is subjected to mechanical loads. This leads to complex deformations near the tip of notch. The electric fields can lead to the motion of electrical impurities (or ‘dopants’) and is a potential failure mechanism that is currently being researched.

End-to-end Earthquake Modeling/Infrastructure Response To prevent earthquakes from becoming disasters, it is essential to gain a better understanding of how earthquakes originate, how the seismic waves propagate from the source, how they amplify as they enter alluvial basins, and how the built environment responds to such excitation. Professor Bielak is working on different aspects of this problem, including the forward and inverse-based simulation of the earthquake ground motion in large basins (figure 5) using high performance computing, and on the effect of this ground motion on portions of an entire city, including buildings, bridges, and underground structures. In addition, he and Professor Acharya use concepts of dislocation mechanics to study the dynamic rupture process

on faults. The objective is to be able to generate realistic scenario earthquakes that can be used as input in end-to-end, or “rupture to rivets”, simulations.

Coarse-Graining Nonlinear Dynamics of Materials Systems The question of deducing the general form and specifics of the laws governing macroscopic response of materials based on well-established microscopic theories is essentially a mathematical and algorithmic one.

Professor Acharya’s approach to this problem starts from a given fine dynamics with some idea of what time-averaged coarse variables (i.e. time averages of aggregated degrees of freedom) one might be interested in. This microscopic dynamics is augmented by the addition of appropriate forward and backward time-delay variables corresponding to the original set so that an appropriate macroscopic dynamics becomes associated with it that may be computationally approximated. In essence, a practically crucial time-scale separation is induced by the augmentation even if the original dynamics did not come equipped with one. The development and implementation of this methodology involves sophisticated tools from nonlinear mathematics, statistical inference, numerical analysis, database management and data-mining. This work has been successfully applied to small, but difficult, nonlinear problems as proof-of-principle, as recorded in the technical literature.

ith the generosity of Michael and Julia Ellegood, the first ever strategic doctoral fellowship has been established in CEE. The fellowship will support a doctoral student, advised by a team of faculty members, and will target new strategic areas of research where more traditional funding sources may not yet be available.

Department Head Jim Garrett said that “We plan to use this fellowship to investigate new areas of research and it is our distinct honor to have Julie and Mike create such a lasting legacy in support of excellence in research for CEE. We greatly appreciate their generous support of our department.” Although this is the first such fellowship in CEE, it is the department’s intention to raise four additional strategic doctoral fellowships over the coming years.

The Ellegood Strategic Doctoral Fellowship has been awarded for January 2008 to Professors Acharya, Soibelman and Dayal, who will use the fellowship to recruit a doctoral student to work on a simulation tool that is able to predict the dynamic response of a collection of atoms (in sufficient number for engineering applications) and at times scales that are several orders of magnitude greater than the periods of atomic vibration. Such a tool will allow for the tractable simulation of a number of important phenomena related to practical applications, such as fatigue crack initiation/propagation in turbine blades/discs and the design of reliable microelectromechanical systems (MEMS) devices. The creation of this tool will require both theoretical contributions as well as the development of data management and data mining approaches to support the simulation.

International Programs Established CEE is excited to announce two new international collaborations that were established in 2007. The first international collaboration is with the University of Trinidad and Tobago (UTT). On May 15, 2007, the CEE Department at Carnegie Mellon and the UTT signed a memorandum of understanding (MOU) to establish a collaboration. As described by UTT, they were formed as “a private non-profit entity in order to revolutionize tertiary level education in Trinidad and Tobago in support of the national development thrust towards achieving a more developed nation status.” Their stated mission is “to be an entrepreneurial university designed to discover and develop entrepreneurs, commercialize research and development, and spawn companies for wealth generation and sustainable job creation towards the equitable enhancement of the quality of life of all individuals, families and communities of the Republic of Trinidad and Tobago and the Caribbean”. UTT contacted CEE at Carnegie Mellon to establish a collaboration in the fields of information and communication technology (ICT) and construction technologies. The potential areas of collaboration include enrolling existing or potential UTT staff or students in existing MS or PhD programs at Carnegie Mellon, collaborating in research projects funded by Trinidad and Tobago companies and government agencies, assisting in the development of degree programs, and having UTT’s undergraduate students participate in a summer internships at Carnegie Mellon funded by UTT The second international collaboration is a dual PhD degree program with the Korean Advanced Institute for Science and Technology’s (KAIST) Civil and Environmental Engineering department. The MOU, signed by both CMU President Jared Cohon and KAIST President Suh Nam Pyo on October 5, 2007, reflects a commitment of both universities to explore new research opportunities as well as the joint education program, which enables PhD candidates at Carnegie Mellon and KAIST to earn a degree at each institution. Each PhD student in this program must apply and be admitted to both departments, meet all of the requirements for both PhD degree programs, and create doctoral dissertations that satisfy a committee made up of faculty from both institutions.

This dual PhD degree program opens up a number of exciting possibilities for collaboration between our two departments, which are focused on innovative areas in civil and environmental engineering such as advanced sensing-based systems for infrastructure, sustainable engineering, and environmental nanotechnology. New research opportunities will emerge that both universities can approach together by leveraging each department’s strengths. It will enable us to attract new students into our program who are interested in studying both at Carnegie Mellon and

KAIST. Finally, through these dual degree PhD students, researchers in both programs will be able to make some use of each others research facilities. For more information on these collaborations, please visit www.ce.cmu.edu/graduate/kaist.html.

Green Design Apprenticeship Program Since 2004, the Green Design Institute (GDI), an interdisciplinary research team of colleagues from CEE, Engineering and Public Policy, Mechanical Engineering and the Tepper School of Business, at Carnegie Mellon University has offered the Green Design Apprenticeship Program for local high school students. Each year, a cohort of 15 to 20 students meet for five school days spread over a five-month period. The Apprenticeship continues to be a top choice for students applying for apprenticeship programs, and the number of students participating has grown each year.

The Green Design Apprenticeship introduces students to the principles of green design, including the connections between engineering and environmental and social issues. Topics cover the breadth of the field and are based on research conducted by the GDI. Topics include Life Cycle Assessment, impacts of energy production and consumption, issues regarding water quality and quantity, future transportation alternatives, and advances in green building. Students use the on-line Economic Input-Output Life Cycle Assessment tool (www.eiolca.net), determine their personal electricity consumption, compare feasibility of transportation vehicles and fuels, and debate public infrastructure needs for water and electricity. A highlight of the program is a tour of the CMU campus and the extent of green design incorporated into new construction and building renovation projects, where students see firsthand how the concepts they have learned are engineered into buildings.

The program is part of a broader apprenticeship program, the AIU3 Gifted and Talented Apprenticeship Program, organized by the Allegheny Intermediate Unit, a regional educational service agency of the Pennsylvania Department of Education. The program couples students with professionals in many fields to explore future career possibilities.

The Green Design Apprenticeship is supported through the National Science Foundation as outreach to broader audiences on various Green Design Institute grants, and through funding from the Steinbrenner Institute for Environmental Education and Research (SEER).

CEE NEWS Continued The site has been in use since the first available day. It provides a unique experience setting above a hillside and being surrounded by glass.

Spring 2007 Design and Construction Project

-LARRY CARTWRIGHT

The spring 2007 Design and Construction project was a garden and seating area in honor of the late Allen Newell. Professor Newell taught at Carnegie Mellon for 36 years and is considered one of the founders of the fields of artificial intelligence and cognitive science. The project was funded by his wife, Mrs. Noël Newell.

The project site was located on a below-grade hillside on the north side of Newell Simon Hall. This building was formerly owned by the U.S. Bureau of Mines and was the center of their national coal research.

The university purchased it from the U.S. government in 1985. On the east and west side of the hillside are matching 12 foot diameter chimneys that have been truncated and capped. The caps are 4 feet below existing grade. In 1993, the Design and Construction project was the installation of a fire escape and deck atop the west chimney. The Newell project site was the east chimney.

The final design was a series of five overlapping squares that spiral down the hillside and terminate on the chimney. The squares increase in size from 6’ by 6’ to 12’ by 12’. In plan view, the squares also rotate counter-clockwise. The four upper squares required caissons for support.

These were drilled by JG Contracting, owned by John Gyurina (CE ’87). Above the caissons, four cylinders were cast in pumpkin colored concrete to match the shape and color of the chimney.

The five square decks were cantilevered structures of charcoal concrete. Each square had built-in planters which required creative placement of the reinforcing steel. To further compound the problem, there was a spiral ramp that extended from the top to the bottom square. The ramp was included to make the design compliant with the Americans with Disabilities Act. This also posed problems in ‘the design’ of the cantilevered squares. In total, the students placed 38 cubic yards of concrete.

The ramp and surface of the lower deck were fabricated of Trex®, a recycled wood and plastic product. All squares were surrounded by 42” high glass walls. The glass was ½” thick, tempered safety glass. The glass enclosure provides an ethereal look to the entire structure.

An existing concrete wall on the east side of the site was covered with a “living wall” system. This is a system of stainless steel angles and cables which enable creeping plants to grow up the wall without contacting it. Virginia Creeper plants were planted at the base of the wall.

The remaining hillside was planted with assorted shrubs and 1500 ivy plants.

The students also designed and built three benches for the lower deck. They are made of cedar and have unique swiveling mahogany armrests which could accommodate a lunch or a laptop computer. The lower deck also includes two ground-fault convenience outlets and a stainless steel base for the future addition of an umbrella.

New M.S. Program in CEE Established A new M.S. program has been established in the field of Global Sustainable Construction. This new program, offered by CEE, seeks to educate future decision makers in the construction industry about how the global and local drivers of sustainability are likely to affect their decisions. The suggested core curriculum introduces students to the economic, environmental, and social implications of the construction industry. Participating students will learn how to make decisions specifically geared towards sustainable construction practices. The ability to define sustainability with respect to local as well as global effects is important for achieving such global sustainable construction practices.

Courses on construction project management, the global construction process, economic planning, environmental life cycle assessment, and sustainability will provide the foundation for sustainable construction process decision making. The courses in this program are taught by a cross-disciplinary team of professors, including faculty in CEE’s Advanced Infrastructure Systems (AIS) and Environmental Engineering Science and Management (EESM) groups.

The new members include undergraduate students Katherine Basta, Katelynn Benton, Daniel Cox, Christopher Fornataro, Paz Gilboa, Thomas Hendrickson, Nolan Kurtz, Jennifer Lawrence, Albert Penksa, Patrick Snyder, Andrew Stocchetti, Corey Tucker and Professors Susan Finger and Kelvin Gregory.

Undergraduate Students Study Hazardous Art Supplies For some time, Carnegie Mellon University has stressed ‘green’ awareness in its practices and attitudes.

Accordingly, the campus art store expressed interest in assessing the type of art products offered, with hopes to provide greener alternatives wherever possible. As part of Professor Susan Finger’s CEE Projects course, CEE students Amanda Mitchell and Pamela Torres, along with Information Science student Devin Blais conducted abbreviated Life Cycle Assessments for 20 art supplies sold in the campus art store.

The products, known to be hazardous when handled improperly, were analyzed for impacts to health and environmental impact from the moment the product arrives on campus to the moment it leaves. The team delivered a database summarizing the results of the life cycle assessment, safety risks, safe practices, proper disposal and possible alternatives. With this information in hand, the art store is better equipped to make informed decisions regarding future art supply purchases.

The project continued after the end of the course with funding from a Small Undergraduate Research Grant (SURG) offered through the Undergraduate Research Office.
