Hill Engineering featured in Railway Track & Structures – August 2022

by Camille Fowler

We recently learned that some hole drilling method and contour method results were highlighted in the August 2022 issue of Railway Track and Structures. The article is titled Residual stress investigation of ultrasonic impact treated and untreated thermite welds.

Presentation: 1st ASTM Bearing and Transmission Steels Technology Symposium

by Robert Pires

Hill Engineering will be presenting at the upcoming 1^st ASTM Bearing and Transmission Steels Technology Symposium in New Orleans, LA on November 2^nd through the 16^th. We invite you to come see us.

Held at the Sheraton New Orleans Hotel, the objective of the symposium is to bring together rolling bearing and transmission steel practitioners from the steel industries, rolling bearing and transmission product producers, research and development institutes and academia, to present the latest steel technologies and developments.

The abstract for Hill Engineering’s presentation, titled Efficient Residual Stress Quantification in M50NiL Bearing Steel, is included below.

New Publication – Near Surface Residual Stress Measurement Using Slotting

by Adrian DeWald

Hill Engineering recently published new research presenting an innovative new way to measure near-surface residual stress more reliably than conventional techniques. The paper is titled Near Surface Residual Stress Measurement Using Slotting and appears in Experimental Mechanics. The abstract text is available here along with a link to the publication.

by Adrian DeWald

Hill Engineering will be presenting at the upcoming SEM Annual Conference and Exposition on Experimental and Applied Mechanics in Pittsburgh, PA on June 13^th through June 16^th. We invite you to come see us!

This conference focuses on all areas of research and applications pertaining to experimental mechanics, and has evolved to encompass the latest technologies supporting optical methods; additive & advanced manufacturing; dynamic behavior of materials; biological systems; micro-and nano mechanics; fatigue and fracture; composite and multifunctional materials; residual stress; inverse problem methodologies; thermomechanics; and time dependent materials. Hill Engineering’s presentation will include a summary of recent work related to residual stress measurement using slotting. The abstract text is presented below.

New Rapid Forge Design Article in FIA Magazine

by Robert Pires

Our Rapid Forge Design (RFD) software has generated a substantial amount of buzz since it’s release last year. If you’ve been keeping up with our social media accounts, you’ve probably caught us highlighting its key features and ease of use, especially through our demonstration video in which creator John Watton goes step-by-step through the closed-die impression forging design process.

For those who want a more comprehensive rundown of the software’s features and abilities, as well as plans for future design modules, John recently published an article in Forging Industry Association magazine, where he gives a history of how RFD came to be, and how it serves forgers and forging consumers.

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.
