Name That Aircraft Challenge winner: Gerold Arheilger
Everybody put your hands together for 2018’s #Namethataircraft winner, Gerold Arheilger! For those of you who were unaware, we began a bi-weekly competition this past year where our twitter followers scored points for identifying photographs of aircraft on our twitter account. Continue reading Name That Aircraft Challenge winner: Gerold Arheilger
Hill Engineering Holidays: 2018
The holidays are always a special time at Hill Engineering. The end of the year is a busy time for everyone and the annual holiday party at Hill Engineering is always something to look forward to. In addition to residual stress measurements; putting up decorations around the office, playing festive music, and putting on our best holiday sweaters were just some of the things going on during this time of year. Continue reading Hill Engineering Holidays: 2018
Welcome George Kaschner
We would like to welcome George Kaschner to Hill Engineering. George comes to Hill Engineering with more than 30 years of experience, most recently from Los Alamos National Laboratory. George has degrees in Applied Physics and Materials Science & Engineering, and received his Ph.D. from UC Davis in 1997. Since then, he has accumulated significant experience in materials science, materials testing, and data analysis. Continue reading Welcome George Kaschner
Overview of a strain gage
We talk about strain gages a lot in our blogs, vlogs, and all over our website. That’s because strain gages are a crucial element of the work we do at Hill Engineering. Our little rectangular friends are very important sensors for residual stress measurements. That something so small can be so important is astounding, but how exactly do strain gages work? Continue reading Overview of a strain gage
ASIP conference 2018
Hill Engineering is presenting at the upcoming 2018 United States Air Force Structural Integrity Program Conference (ASIP) in Phoenix, AZ. Our talk will focus on residual stress evaluation in legacy aircraft cold expanded fastener holes. The 2018 ASIP Conference is specifically designed to bring together the world leaders in the area of aircraft structural integrity, to disseminate information on state-of-the-art technologies for aircraft structures in both the military and civilian 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 ASIP conference 2018
Hill Engineering meets Big Trees
Nothing beats the great outdoors, if you ask me. Well, maybe residual stress measurements, but that’s a different story. This summer, the Hill Engineering group drove down to Calaveras Big Trees State Park to take in the sights and sounds of nature, complete with campfire songs, S’mores, and a weekend filled with fun. Continue reading Hill Engineering meets Big Trees
Hill Engineering open house
Hill Engineering recently held an open house at our new office location in Clearfield, UT. The event was a success, allowing us to show off our new office to our customers and partners in the local area. Continue reading Hill Engineering open house
Case Study: PSR biaxial mapping
Hill Engineering recently posted a new case study detailing our research into an extension of the contour method we call PSR biaxial mapping. This new technique generates two-dimensional maps of additional residual stress components over the same plane as the original contour method measurement. Continue reading Case Study: PSR biaxial mapping
Residual stress measurement techniques
Residual stresses exist in most materials and structures. Processes like forging, rolling, extruding, quenching, additive manufacturing, machining, and welding can cause residual stresses to develop. These stresses can influence the way that materials perform (e.g., fatigue, fracture, distortion, and corrosion). There are many different residual stress measurement techniques available to quantify residual stresses. The following are some examples of common measurement techniques.
