Hill Engineering recently performed various residual stress measurements on nickel and aluminum specimens to support a project from the Materials & Processes Engineering group at Pratt & Whitney. The results will be presented by Pratt & Whitney at the International Conference on Residual Stress, happening October 20-23, 2025, in Detroit, MI. If you are planning…

After a busy summer filled with high-temperature residual stress measurements, the Hill Engineering team took some time to relax and recharge with a well-deserved pool party. Nothing beats cooling off in the water after long days in the lab, and this year’s gathering gave us the perfect chance to enjoy some sunshine and spend quality…

As was previously discussed, Hill Engineering was recently awarded ISO17025:2005 accreditation for our Quality System. Developing a Quality System that is compliant with ISO is a significant effort, and at Hill Engineering we took it as an opportunity to improve the quality and documentation of our laboratory residual stress measurement services. Here’s a look back…

Fatigue is one important failure mode that guides the design and engineering of aircraft structure. As we have discussed previously aircraft are often manufactured using rivets and fasteners, which require drilling many holes in the structure during assembly. The holes act as stress concentrations, which tend to be locations where fatigue cracks are found. Compressive…

Hill Engineering recently moved into a new facility in Rancho Cordova, CA. The new facility features a combination of laboratory, research and development, and office space; all of which are important as we work tenaciously to meet the needs of our current projects, while at the same time keeping an eye towards innovation and new…

Aircraft undergo complex loading during their operation and lifecycle. For example, take off, landing, turbulence, and flight/ground maneuvers are all instances where significant loading occurs. The cyclic loading and unloading activates a failure mechanism called fatigue, which is most prevalent at the highest stressed regions. Many aircraft are assembled using riveted construction, whereby small holes…

Fracture and fatigue are important material performance issues that Hill Engineering examines on a regular basis. Hill Engineering recently contributed to a publication titled “Investigating and interpreting failure analysis of high strength nuts made from nickel-base superalloy.” The publication includes a detailed review of work performed to understand the failure of these fracture critical nuts.…

2016 was an exciting year at Hill Engineering. We accomplished so much and we wanted to take a moment to recognize some of the highlights. Early in the year, we were in the middle of Hill Engineering’s largest ever facilities planning/construction project. We had just selected our new office location and needed to plan and…

The Hill Engineering employees took a quick break from all the residual stress analysis to partake in a few fall-themed festivities this season. We recognize that enjoying quality time together is an important way to strengthen our resolve as a team. What better way to do that than through everybody’s favorite activities: pumpkin carving and…
