When we’re not performing residual stress measurements, some of the HE team members love spending time with their furry friends! Josh Hodges is no exception. He lives with his two German Shorthair Pointers, Saaz and Barley, ages 12 and 3 respectively.

Contour Method 101: Two-Dimensional Mapping of Residual Stress

We talk a lot about the residual stress measurement techniques we employ at Hill Engineering. One of the most commonly used is the Contour Method! Invented in the year 2000, and patented by Los Alamos National Laboratory, the contour method measures 2D residual stresses over a planar surface.

HE Pet Spotlight: Eggs and Pancake

I think we can all agree that eggs and pancakes are two of the best breakfast foods out there. They are even better when they’re the names of two cats that live with another Hill Engineering family. Seven-year-old Eggs and three-year-old Pancake take up residence with Eric and his wife, Lucy, where they like snuggling to their hearts’ content in their outside sunroom.

New Publication – Measurement Layout for Stress Mapping Using Slitting

Hill Engineering recently published new research detailing our efforts to optimize the experimental technique for our PSR Biaxial mapping process, which generates a 2D map of residual stress. The paper is titled Measurement Layout for Residual Stress Mapping Using Slitting and appears in Experimental Mechanics. The abstract text is available here along with a link to the publication.

In the Field with Ryan: On-site Residual Stress Measurements

While we at Hill Engineering take pride in our ability to perform high quality residual stress measurements in our laboratory, we recognize that not all parts and projects can be easily transported.

That’s where we bring the measurements to you with our Residual Stress Field Team. Our laboratory engineers are capable of performing residual stress measurements across the globe, and have done so on many occasions.

Special Issue of Experimental Mechanics

We are in the process of organizing a special Issue of Experimental Mechanics, the journal of the Society for Experimental Mechanics. The issue will be devoted to Advances in Residual Stress Technology in honor of Prof. Drew Nelson of Stanford University, for teaching several thousand engineering students about the importance of residual stresses and for developing new optically based approaches for measurement of residual stresses, along with studies of residual stress effects on fatigue. To date, we have accepted proposed paper topics from almost 20 world-leading authors from around the globe.

Deep-Hole Drilling on a bent-beam specimen

In 2019 Hill Engineering licensed VEQTER Ltd.’s world-leading Deep-Hole Drilling (DHD) technology. Under this agreement, Hill Engineering is delivering state-of-the-art DHD measurements within the North and South American Continents. Results from a recent DHD measurement on a bent-beam specimen are shared in this blog post.

Turbine Engine Technology Symposium 2021

Hill Engineering will be presenting at the upcoming Turbine Engine Technology Symposium (TETS) scheduled for September 15-17, 2021 at the Dayton Convention Center. We invite you to come see us.

The TETS Symposium is a biennial forum where the United States’ turbine engine community gathers to review and discuss the latest turbine engine technology advances. The Symposium draws an audience of approximately 1000 engineers, scientists, managers, and operational personnel from throughout the turbine engine community, including the Army, Navy, Air Force, NASA, DARPA, DOE, FAA, engine and aircraft manufacturers, material and component suppliers, and academia.

Hill Engineering’s presentation will include a summary of recent work related to predicting residual stress and airfoil distortion from shot peening and laser shock peening. The abstract text is presented below.
