I am reaching out again for assistance with the chapter on failure analysis for our Residual Stress Handbook project. This project is part of the Residual Stress Technical Committee that formed in 2020.
Many of you have already provided guidance, and I truly appreciate the help. I have attempted to put together an outline. Case histories will be covered in a separate chapter. Together, we can get a solid chapter that will advance knowledge of how residual stresses cause failures and how to detect them.
Please comment/expand/modify the above so we can cover the topic fully. I would like to see a collaboration between FAS and RSTC. I feel it would be a win/win for both entities.Thank you!Beth
In addition to warpage in heat treatment (due to residual stress from casting or previous processes), distortion can also occur during machining due to residual stress from heat treatment, and after failure, which can affect the failure investigation. Residual stresses can also be introduced by the failure if the distortion is severe enough and introduced or relieved if the failure involved high temperatures.
