HE measurement data presented at upcoming ICRS 12
Hill Engineering recently performed various residual stress measurements on nickel and aluminum specimens to support a project from the Materials & Processes Engineering group at Pratt & Whitney. The results will be presented by Pratt & Whitney at the International Conference on Residual Stress, happening October 20-23, 2025, in Detroit, MI. If you are planning…

Legacy Post: Residual stress in welding (Sep 2016)
Welding is a very common manufacturing process that is used to join materials together to form assemblies and systems. In many cases the welded joints are large, have reduced material properties (e.g., stress corrosion cracking resistance, fracture toughness), and contain defects. The welded joints tend to be critical locations in terms of design and sustainment.…

Legacy Post: Happy Birthday to the Contour Method! (Aug 2016)
Today marks 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 this date (August 16th) in 1999 by Mike Prime at Los Alamos National Laboratory. The most significant feature of the contour method is its…

Residual Stress Measurement Inside A Welded Pipe (May 2016)
The inner diameter of pipes is a critical location for design and performance assessment. Corrosion, fatigue, and stress corrosion cracking often attack the pipe inner diameter, which can lead to leakage and possible failure of the system. Tensile residual stresses in welded pipe joints can have a significant impact on structural integrity and performance because…

Legacy Post: What is Residual Stress? (May 2016)
What is residual stress? That’s a very common question when you work at Hill Engineering. Many of our customers, friends, colleagues, and family members like to ask us questions about residual stress including: What is residual stress? How do you measure it? How does residual stress affect material performance? If you have questions about these…
