ASIP 2021 Presentation: Development of a Residual Stress Standard

by Adrian DeWald

At the recent United States Air Force Structural Integrity Program Conference (ASIP) in Austin, TX, Hill Engineering co-authored a presentation titled Development of a Residual Stress Standard. The Aircraft Structural Integrity Program (ASIP) Conference is specifically designed to bring together the world leaders in the area of aircraft structural integrity and to disseminate information on state-of-the-art technologies for aircraft structures in both the military and civilian fleets. Below is the abstract from the presentation along with a link to the full conference slides.

Contour Method 101: Two-Dimensional Mapping of Residual Stress

by Robert Pires

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.

New Publication – Measurement Layout for 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.

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.

ASM Heat Treating Society 31st Annual Conference And Exhibition

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.

A Delightful Celebration of Five Golden Years

by Robert Pires

This week, we’re celebrating five years at our Gold Canal Drive facility in Rancho Cordova, California. Hill Engineering acquired the building in 2016 to meet the rising demand for residual stress measurement, fatigue analysis and design, and residual stress engineering services.

Hill Engineering Now Admitted to Forging Industry Association

by Adrian DeWald

Hill Engineering was recently admitted to the Forging Industry Association (FIA). For more than 100 years, the FIA has been helping forging companies in North America to increase their global competitiveness. FIA’s producer member companies manufacture approximately 75% of the custom forgings volume produced in the United States, Canada and Mexico. Its supplier members manufacture materials and provide services used by the forging industry. Together, FIA’s 200 members comprise the only trade association dedicated to promoting and serving the forging industry in North America.
