Hill Engineering Makes the Cover of Experimental Mechanics

Previously, we highlighted a new publication discussing our efforts to optimize the experimental technique for our PSR Biaxial mapping process, which generates a 2D map of residual stress, titled Measurement Layout for Residual Stress Mapping Using Slitting. We recently learned that the presented results made the Volume 62, Issue 3 cover of Experimental Mechanics for March 2022. Way to make it happen, Hill Engineering! If you’re interested, the abstract text is available below along with a link to the publication.

New Rapid Forge Design Article in FIA Magazine

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.
