We are thrilled to celebrate Eric Summer’s tenth work anniversary at Hill Engineering! Since joining the team in July 2014, Eric has made invaluable contributions to our design and automation efforts. His journey began in a technical role, and while his core responsibilities have remained the same, Eric has become the go-to person for fixing “random stuff” around the office and tackling odd jobs that fall outside traditional roles.

In the ever-evolving landscape of materials science and engineering, on-site solutions are an important component of residual stress testing. That’s why we at Hill Engineering have a dedicated residual stress field team, capable of traveling directly to customers’ locations in order to deliver the same precision and data quality of our in-house residual stress measurements.

Hill Engineering is officially going global!
We are proud to announce we’ve been issued our first Japanese patent for the DART™, our Device for Automated Residual stress Testing.
Continue reading Hill Engineering issued first Japanese patent for the DART!TrueSlot® is an innovative technique for measuring near-surface residual stress that is more reliable than conventional techniques.
TrueSlot® is a residual stress measurement technique for generating a profile of residual stress versus depth from the material surface. The stress computation is similar to slitting but offers more sensitivity near the surface due to the proximity of the strain gage.
Additionally, TrueSlot® is globally less invasive than slitting because the volume of removed material is localized to the surface and does not typically extend through most of the specimen thickness.
The physical application of TrueSlot® is like hole drilling, however instead of a shallow hole being milled into the body of a specimen containing residual stress, the material removed is a shallow slot. The strain released with each incremental slot depth is measured near the slot using a strain gage.
TrueSlot® is useful for
TrueSlot® was found to have better repeatability when compared with conventional x-ray diffraction.

TrueSlot® measurements are performed using our DARTTM system for automated residual stress measurement.

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.
