Residual short course at SEM conference

We will be teaching a short course on residual stress on June 12, 2022 at the SEM Experimental Mechanics conference in Pittsburgh. 

See below and https://sem.org/annual (under PROGRAMS/COURSES) for details.

Residual stress short courses don't happen too often. The course should be appropriate for students, industrialists, and researchers. Hope you can make it. The proceeds all benefit SEM.

Residual Stress 101

Description:
This course aims to cover a broad, practical introduction to residual stresses for students, researchers, and industrialists with an interest 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.
