CAE Based Fatigue, Durability and Damage Tolerance With a Particular Emphasis on Dynamic Systems and Vibration Environments A State of the Art Perspective by Dr. Neil Bishop
(Author of the NAFEMS Book, Finite Element Based Fatigue Calculations)
Course Number: PAT319 Course Presenter: Dr. Neil Bishop (author of the NAFEMS Book, Finite Element Based Fatigue Calculations) Summary: This course involved the mixture of 3 distinct topics:
1)
CAE
2)
Dynamics
3)
Fatigue Analysis
Length:
3 Days
Cost:
$1425 (U.S. only) £1125 (UK) €1275 (Europe)
Prerequisites: An interest in the subject
The course will present a unique perspective on this by highlighting the importance of the integration of the subjects, which can then be used to show this is a situation where the combined capability really is more than the sum of the parts. In order to do this, a state-of-the-art view of CAE based fatigue, durability and damage tolerance calculations will be presented with a particular emphasis on dynamic systems and
vibration environments (such as that defined in military standard MILSTD-810). Although MSC products will be used to show example problems, the course material will be independent of any software products and generally focused on the technology rather than specific software products. Furthermore, although much of the material presented will be at an advanced level, there will be no prerequisite other than an interest in the subject.

Agenda
Part 1
• History of Fatigue Methods and their Integration into the CAE Environment • The Concept of FE Based Fatigue Analysis • Commercial Applications • Background to Dynamics for Fatigue Analysis • Step-by-Step Process for Static and Dynamic Models (Both Time and Frequency Domains) • Some Frequency Domain Dynamic (Vibration Fatigue) Examples
Part 2
• Background to Fatigue (Stress Based) • Materials Considerations • Loading Considerations • Stress-Life Based Fatigue in More Detail • Strain Life Based Fatigue • Fracture Mechanics and Crack Propagation (Brief Treatment Only) • Accelerated Testing Techniques • Composites and Non-Metallic Materials • An Introduction to Weld Analysis, Wheels Fatigue, Multiaxial Fatigue and MBS
Part 3
• Vibration Environments • Frequency vs Time Domain • System Transfer Functions (Frequency Domain) • Classifying Time Signals and PSD’s • Working Directly with PSD’s • Options for Calculating Fatigue Life from PSD’s • Acoustic (Geometrically Non-Linear) Fatigue
Instructor Background: Neil wrote the book, Finite Element Based Fatique Calculations for NAFEMS more than 11 years ago and since then he has been actively involved with a variety of applications of the technology. Neil Bishop has a PhD in Mechanical Engineering and has published over 30 academic papers and books related to fatigue and durability, dynamics and renewable energy. These included the only book written exclusively on FE Based Fatigue. Neil worked for 10 years as an academic within the UK university system and successfully

supervised 6 international PhD students. He pioneered the use of innovative laboratory based methods for teaching mathematics and dynamics. Neil also managed several research programs for the UK and other European governments. In fact, he was called to act as an expert witness and technical expert for both the UK and Dutch governments on several occasions. Neil has also recently worked on a SBIR project for the US Air force on acoustic fatigue.
