Short Course Announcement – Residual Stress 101

The upcoming SEM Annual Conference and Exposition on Experimental and Applied Mechanics will include a Pre-conference Course titled: Residual Stress 101. The residual stress short course is scheduled for Sunday, June 12, 2022, from 9:00 a.m. to 5:00 p.m.

The course aims to cover a broad, practical introduction to residual stresses for students, researchers and industrialists with an interest in the subject. The course will be taught by Michael Prime, Michael Hill, Adrian DeWald, Luliana Cernatescu, Jeff Bunn, and Gary Schajer. Registration is currently open through the SEM Website.

The Residual Stress 101 course will cover a broad, practical introduction to residual stresses for students, researchers, and industrialists interested in the subject. We cover the most practically important aspects of residual stress; things that are fairly simple but often counterintuitive, poorly understood, or just not widely known. Most of this material is not covered by coursework for engineers or material scientists.

We will answer the most important questions:

  • What are residual stresses and where do they come from?
  • What effects do they have?
  • How are the stress components throughout a body interrelated?
  • How can you measure residual stresses?
  • How can you use residual stress knowledge in models to predict failures or other issues?
  • How can you use superposition to simplify many calculations?

Along the way we will point out pitfalls to avoid and mistakes that appear in the literature.
