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…

Legacy Post: Residual Stress Calculation (July 2017)
In a recent blog post we discussed the question: what is residual stress. As a follow-up, today we are addressing the topic of residual stress calculation. Once you understand the concept of residual stress and are ready to account for its effect on material performance it’s important to quantify the residual stress that is present…

Legacy Post: Building a Quality System (Feb 2017)
As was previously discussed, Hill Engineering was recently awarded ISO17025:2005 accreditation for our Quality System. Developing a Quality System that is compliant with ISO is a significant effort, and at Hill Engineering we took it as an opportunity to improve the quality and documentation of our laboratory residual stress measurement services. Here’s a look back…
