New Publication – Measurement Layout for Residual Stress Mapping Using Slitting

by Adrian DeWald

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

by Robert Pires

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

by Adrian DeWald

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.

On our last pet spotlight, we introduced you to Potato, the very active Syrian dwarf hamster. Keeping with the “food” theme, our next feature is about Quiche, the four-year-old, all-black domestic short hair who lives with her family: Caleb and Mari.

Deep-Hole Drilling on a bent-beam specimen

by Ryan Tucci

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

by Adrian DeWald

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.

by Adrian DeWald

Hill Engineering is presenting “Evaluation of forging process induced residual stress in aluminum die forgings” at the ASM Heat Treating Society 31st Annual Conference and Exhibition. Held Tuesday, September 14, 2021 – Thursday, September 16, 2021 in St. Louis, MO, Heat Treat is the premier conference and expo for heat treating professionals; attracting global innovators, researchers, influencers and decision makers from around the world. This year’s conference and expo will feature two-and-a-half days of face-to-face networking opportunities with approximately 200 heat treat exhibitors/companies. The abstract text is presented below.

Introducing the DART – HE Vlog

by Robert Pires

Our latest vlog highlights the DART™, our turn-key, industry-leading tool for precise, reliable, and efficient near-surface residual stress measurements. The Device for Automated Residual stress Testing is capable of multiple measurement techniques including hole drilling and TrueSlot®. This flexibility allows for easy adaption as new applications arise.

Case Study: DART – automated residual stress measurement

by Robert Pires

Our latest case study highlights the many benefits of the DART™ automated measurement system, a tool we at Hill Engineering developed specifically to improve near-surface residual stress measurement techniques such as hole drilling and TRUEslot®.

HE Pet Spotlight: Potato the Hamster

by Robert Pires

Even though her paws are roughly the size of a strain gage, don’t expect her to perform any residual stress measurements! Our next pet spotlight is all about Hill Engineering’s smallest fuzzy friend, Potato the Syrian dwarf hamster!
