Legacy Post: The Contour Method: Celebrating A Milestone in Residual Stress Measurement (Aug 2017)
This week we mark a major milestone in the field of residual stress measurement. The contour method, one of the most useful and advanced residual stress measurement techniques, was first successfully implemented on August 16th, 1999 by Mike Prime at Los Alamos National Laboratory. The most significant feature of the contour method is its ability…

Legacy Post: Residual Stress in Additive Manufacturing (Feb 2018)
In previous blog posts we have discussed various issues related to residual stress in welding. Here, we’ll follow up with a more detailed look at residual stress in additive manufactured parts, which is a form of welding. Additive manufacturing processes, including powder and wire-fed E-beam and laser, produce residual stress as an undesired consequence. Residual…
