Advances in Residual Stress Technology in honor of Drew Nelson

by Adrian DeWald

A special Issue of Experimental Mechanics on Advances in Residual Stress Technology in Honor of Drew Nelson was recently published. The Special Issue recognizes Dr. Nelson, Mike’s PhD advisor at Stanford University and a leader in the residual stress community, on becoming emeritus after 40 years of research contributions and teaching on the experimental determination of residual stresses and their effects on fatigue.

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.

Pipe Corrosion Inspection: Hill Engineering in the field

by Hill Engineering

Eric Summer and I recently packed up the DART repair tool for a trip down to Naval Base Ventura County in Port Hueneme, CA. There, we participated in the Navy’s Repair Technology Exercise, or REPTX 2022. Onboard the Navy’s Self Defense Test Ship (SDTS), Hill Engineering demonstrated how the DART repair tool can be applied as an industrial maintenance solution.

HE Pet Spotlight – Sunshine and Malibu

by Robert Pires

When we’re not performing residual stress measurements, some of the Hill Engineering team members love spending time with their furry friends! This is true for Debra LaChappell who lives with her golden retriever lab mix Sunshine, and her cat, Malibu!

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.

Welcome to the team, Jesse!

by Robert Pires

Join us in welcoming Jesse Guymon to the Hill Engineering team!

Jesse comes to us with 7 years’ engineering experience developing and designing tools, components, and assemblies with Autoliv. During his time with the automotive safety systems company, he fulfilled his role as Design Engineer with panache, utilizing SolidWorks to improve manufacturing efficiency through solid modeling.
