New Video Explaining the Contour Method Residual Stress Measurement Technique
Understanding residual stress is essential to predicting how manufactured components will perform in the real world. To help engineers and manufacturers better understand one of the industry’s most powerful measurement techniques, Hill Engineering has released a new video exploring the Contour Method for residual stress measurement in detail. The Contour Method provides a two-dimensional map…

Legacy Post: Understanding Residual Stress: a brief definition (Mar 2018)
Residual stress definition – residual stress is defined as the stress that is present in a material in the absence of externally applied loading. Residual stresses often form during manufacturing and are typically an unintentional byproduct of a manufacturing process. As engineers we care about residual stresses because they affect material performance. Because they are…

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…

Milestone 10th Anniversary at Gold Canal Facility
Last week, we highlighted a legacy post celebrating our first anniversary at (what was our) new location in Rancho Cordova. Today, we’re updating that post for the milestone Tenth Anniversary on Gold Canal Drive! Originally, we moved into our current location due to an increased demand for office, laboratory, and storage space. For years, our…

Legacy Post: Compressive Residual Stress (Nov 2017
We recently answered the question: What is residual stress? As a follow-up for all of our interested readers, today we are addressing the topic of compressive residual stress. Once you understand the concept of residual stress, which is stress that is locked in a material during manufacturing, it is important to distinguish between compressive residual…
