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.

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.

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.

Hill Engineering is proud to support the USAF and their objective to advance damage tolerance analysis methods through the Engineered Residual Stress Implementation (ERSI) workshop. At this year’s ERSI meeting, Hill Engineering will meet with other stakeholders in the USAF aircraft community to review progress over the past year towards implementation of engineered residual stress in the USAF fleet. Continue reading Engineered Residual Stress Implementation workshop 2018

This year’s AFGROW User Workshop will be hosted at the Weber State University Center in Clearfield, UT on September 11-12, 2018. The first annual BAMF workshop will take place at the end of the workshop in the afternoon on September 12th. The BAMF workshop will include presentations on the current work being accomplished by BAMF, recent updates, and a discussion about future plans. If you would like to participate in either the AFGROW or BAMF workshop please register for the meeting at the link above. Continue reading BAMF User Workshop 2018

Hill Engineering’s new facility in Rancho Cordova, CA features a combination of laboratory, research and development, and office space. Our primary conference room is named in honor of Mike Prime, the inventor of the contour method. The Prime Room stands as a tribute to the creativity, insights, and support that Mike Prime has provided to Hill Engineering over the years. One of our favorite pieces on display in the Prime Room is one half of the specimen that was used for the first successful contour method measurement. Continue reading The first contour method measurement specimen

The first half of the year has definitely flown by for Hill Engineering. When we are not performing residual stress measurements like the contour method or the hole drilling method, we have a few social events and activities throughout the year to help us unwind after a long day’s work. Continue reading Hill Engineering fun

This week, we have uploaded a new vlog to Hill Engineering’s YouTube channel revolving around a particularly handy residual stress measurement technique. The hole drilling measurement method is one of our most popular residual stress measurement options, and involves the incremental drilling of a small hole into the surface of a specimen. Watch the video below and read on to learn more about the hole drilling method. Continue reading Hole drilling residual stress measurement method

At Hill Engineering we work with residual stress on a daily basis. Ring Core is one of the techniques that we use for residual stress measurement. Ring Core is capable of measuring residual stress over depths spanning the near-surface to bulk regions, and can be applied to quantify the average residual stress over the depth of a drilled core. Ring Core is portable, and can be applied under a variety of circumstances, including in the field. Hill Engineering uses Ring Core measurements to support process development and quality control. Ring Core measurements can be performed in our laboratory or at your site, to your specifications. Continue reading Ring core
