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.

Over the past few months, we’ve highlighted a handful of employees and the hobbies they’ve either had for a while or ones they’ve picked up recently – when they aren’t solving all of the world’s residual stress related challenges. Our latest spotlight shines on Hill Engineering’s resident author, RD Pires (or Robby, as he’s come to be known by in the office), and his almost life-long passion of writing. I got the chance to interview Robby virtually where we talked about his latest novel, A Vast, Untethered Ocean, his inspiration, and his experience with self-publishing.

Hill Engineering recently participated in the virtual 2020 United States Air Force Structural Integrity Program Conference (ASIP). The 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. Hill Engineering’s presentation included a summary of recent work related to developing a digital quality assurance record for typical aircraft maintenance processes like hold hole expansion. The abstract text is presented below along with a copy of the presentation slides.

Hill Engineering recently published new research detailing our efforts to quantify uncertainty for hole drilling residual stress measurements. This new approach provides a more accurate estimate of the measurement uncertainty associated with hole drilling. The paper is titled Precision of Hole-Drilling Residual Stress Depth Profile Measurements and an Updated Uncertainty Estimator and appears in Experimental Mechanics. The abstract text is available here along with a link to the publication.
