About OU - Fast Facts • The Princeton Review ranks OU in the top 10 in the nation in terms of academic excellence and cost for students. • OU has won awards for new initiatives to create a sense of family and community on campus. OU is one of the very few public universities to twice receive the Templeton Foundation Award as a “Character Building College” for stressing the value of community. • The number of endowed faculty has increased from 100 to 544 positions in the past 15 years, demonstrating a strong commitment to excellence. • Private fundraising records continue to be set by the university, with more than $1.75 billion in gifts and pledges since 1994, which has provided funding for dramatic capital improvements, the growth in faculty endowment and student scholarships.

• The University of Oklahoma maintains one of the three most important collections of early manuscripts in the history of science in the United States. It includes Galileo’s own copy of his work, which first used the telescope to support the Copernican theory, with corrections in his own handwriting. • Since its creation in 1998, OU’s Office of Technology Development has created 36 companies that have generated more than $84 million in capital, more than $10 million in cash and more than $30 million incurrent estimated equity value for the university. • The University of Oklahoma has consistently been designated as one of America’s 100 Best College Buys by Institutional Research & Evaluation, an independent higher education research and consulting organization.

Aerospace and Mechanical AME/CoE History The School of Aerospace and Mechanical Engineering has a rich history at OU. It began in 1905 when the university established the School of Applied Science consisting of Mechanical Engineering, Civil Engineering and Electrical Engineering. Shortly thereafter, James Houston Felgar became an instructor of Mechanical Engineering in 1906. That same year he was appointed to the position of Instructor in Charge. In 1908 Felgar became the Director of the Department of Mechanical Engineering, a position he held until 1925. He also served as Dean of the College of Engineering from 1909 to 1937. It was during this time, James Houston Felgar 1909 to be exact that the College of Engineering was established. Felgar retired in 1937 and was appointed Dean Emeritus and Professor of Engineering. In January 1925 the Engineering Building was constructed. The building was renamed Felgar Hall in 1952 to honor the dedication of James Houston Felgar. An Aeronautical Engineering option was added to the Mechanical Engineering program in 1929, which

spurred the construction of the Wind Tunnel in 1936 as part of a WPA project. These two important milestones in the development of the program took place under the tenure of William Henry Carson. He served as Director of the Department of Mechanical Engineering from 1927 to 1942. Like Felgar, he also served as Dean of the College of Engineering during this time. In 1947 the Department of Aeronautical Engineering was William Henry Carson established within the School of Mechanical Engineering. While still part of Mechanical Engineering, the establishment of the department gave Aeronautical Engineering a much more defined presence in the College of Engineering at OU. The School of Aeronautical Engineering was established as separate from the School of Mechanical Engineering. in 1954. However this name did not last long, in 1959 the school was named the School of Aeronautical and Space Engineering in order to keep up with the national trends. Another building was added in the early 1960’s. Initially called the “Engineering Center,” the building was eventually named Carson Engineering Center in honor of the college’s second dean.

Aerospace and Mechanical AME/CoE History In 1963 the School of Aeronautical and Space Engineering and the School of Mechanical Engineering merged to become the School of Aerospace and Mechanical Engineering, a name that has lasted over four decades. The addition of a research facility for Aerospace and Mechanical Engineering located on the university's north campus, near Max Westheimer Field occured in 1964. At the time the facility primarily housed laboratories for stress analysis, radiant heat transfer studies, aerodynamic research, non-destructive testing, and experiments on advanced propulsion systems. The facility is still used for instruction and research by AME

and the College of Engineering today. The school and college have come a long way from their humble beginnings over 100 years ago. Advances in technology and other changes that have been spurred by the times have no doubt played a role in the shaping of what the school and college have become. With over 100 years of history, the school has a strong foundation to stand on while we enter the next 100 years of engineering at the University of Oklahoma. Always remembering that we are celebrating the past and engineering the future.

Felgar Hall, 1930

Aerospace and Mechanical AME/CoE History George Lynn Cross Reserach Professor Emeritus, Tom J. Love Jr. was the “first” director of the School of Aerospace and Mechanical Engineering. Love was named director upon the merging of the two schools in 1963. Additionally, he received his bachelor’s degree in mechanical engineering from the University of Oklahoma in 1948. It was through his long-standing presence with the College of Engineering and AME that Love was able to further his legacy by writing The College of Engineering: A 70-Year History. The book highlights and tells the stories not only of the administration, but also of the students who experienced the growth of the College and University.

Aerospace and Mechanical Research Collaborations Real-Time Structural Health Monitoring of Large-Scale Structures Faculty: J. David Baldwin (AME), Kim Mish (CEES), Thordur Runolfsson (ECE), Chris Ramsayer (CEES) TECHNICAL CHALLENGES

APPROACH

• Large-Scale structures, e.g. bridges, airframes, machinery, etc. have many potential failure-critical sections that are often difficult to inspect for damage such as cracks • Current practice typically includes applying sensors to the structure (accelerometers, strain gages) collecting large quantities of date, and attempting to deduce the current condition from the sensor time histories • In remote locations, there might not be a ready connection to electrical power, so we must be able to harvest sufficient power from the ambient to power the data acquisition systems

• Updating the data acquisition systems and sensors on two bridges on I-35 (Walnut Creek Bridge in Purcell and Canadian River Bridge in Norman • There will be 20-30 sensors on each bridge with continuous data acquisition and data transmission to an on-campus server; power will be provided by solar panels and grid • Developing algorithms for the fusion of sensor data across the structure to deduce “local” response measure of sufficient fidelity to drive fatigue, fracture, etc. analyses of structural integrity

EXPECTED CONTRIBUTIONS/BENEFITS • Expect to be able to provide the owner of the structure (ODOT in this case) with real-time assessment of the structural integrity • The probabilistic structural health definitions and estimators being developed will benefit the larger SHM community by providing a better framework for estimating the two primary quanitites sought by SHM practitioners, 1) the current residual strength, and 2) the estimated remaining life under current operating conditions

Attaining Engineering Competencies for the Future Through Experiential Learning Faculty: Zahed Siddique, Mrinal Saha, Farrokh Mistree (AME), Patricia Harde, Amy Bradshaw, Xun Ge, and Teresa DeBacker (Educ.) OBJECTIVES

METHODS

• What are the career sustaining metacompetencies that need to be developed in engineering students for the innovation economy? • What steps can be taken so that engineering students become accustomed to thinking along interdisciplinary lines in their approach to solving complex problems?

The “how” for developing this type of skill and expertise in analysis, evaluation, and creative production for unforeseen needs requires authentic experience in tasks that require students to exercise these skills.

•Based on learning and motivational theory, what are proper ways to infuse experiential learning into existing engineering curricula to develop student competencies for the innovation economy?

One way that provides both experience and leverages a number of other advantages for developing these skills is experiential learning. If designed well, experiential learning not only provides authentic opportunity, but also supports self-determined motivation and regulation.

Aerospace and Mechanical AME - Strategic Plan

Mission The mission of the School of AME is to provide the best possible learning experience for students through excellence in teaching, research and creative activity, and service to the state and society, nationally and internationally. This conforms to the vision of the College of Engineering and OU.

Core Values AME faculty has a wide range of research expertise in different areas. AME stakeholders want to view the school as a learning community, defined as a group of people who share common values and beliefs, and are actively engaged in learning together from each other. Such communities have become the template for a cohort-based, interdisciplinary approach to higher education. This is based on an advanced kind of educational or 'pedagogical' design. AME stakeholders embrace the following core values, which will assist in the direction of our future AME activities: • Creating a collegial learning community that empowers each person to rise to his / her full potential • Positioning its faculty to work synergistically with faculty in other schools to facilitate the synergistic creation of economic and intellectual capital • Enhancing programs through the pursuit of excellence in experiential learning and knowledge delivery • Respecting students as junior engineers in a knowledge enterprise that prepares them for multiple careers, while upholding and maintaining high educational standards and requirements • Recognizing that research, development, problem solving and consulting play a role in creating intellectual and economic capital at a university

Vision AME’s vision is to move Towards Distinctiveness and Recognition - Be recognized as a premier learning community of faculty, staff and students that upholds collegiality, and synergistic collaboration in pursuit of academic excellence, and as a community valuing both individual and collective achievements.
