Aircraft Airworthiness & Sustainment 2018

by Adrian DeWald

Hill Engineering is presenting about residual stress evaluation in legacy aircraft cold expanded fastener holes at the upcoming 2018 Aircraft Airworthiness & Sustainment Conference (AA&S) in Jacksonville, FL. The mission of this conference is to identify the challenges and the collaborative work being done within the aerospace community in improving the safety, airworthiness, availability and cost effectiveness of both our military and commercial aircraft fleets. Hill Engineering’s presentation will include a summary of recent work in airframe structures, demonstrating the effect of aircraft service on the residual stress at cold expanded fastener holes. The abstract text is presented below. Continue reading Aircraft Airworthiness & Sustainment 2018

Hill Engineering Vlog: Strain Gaging

by Robert Pires

Strain gages are key tools when performing residual stress measurements. By tracking the electrical resistance change of the strain gage foil, we can evaluate strain through material deformation. In our vlog presented below, we demonstrate how to apply a strain gage on an aluminum tensile specimen. While the setup described in the video is simple, we are capable of applying strain gages to much more complex geometries to fit the needs of our residual stress tests. For more information or any questions about your residual stress needs, please contact us.

Visiting the Utah office

by Adrian DeWald

Last year, Hill Engineering opened a satellite office in Layton, UT with the goal of better connecting with our customers and partners in the local area. Mike and I recently made a trip out to the office to check in and to spend some time working with our excellent team there to better understand and appreciate their outstanding work.
