Hill Engineering is pleased to highlight another featured chapter in the ASM Residual Stress reference, written by our very own Michael Hill, that provides an in-depth look at the Slitting Method for residual stress measurement. The Slitting Method is a powerful technique for determining one-dimensional residual stress as a function of depth through a material.…

We’ve previously talked about fracture surfaces created as a result of material fatigue. Through fatigue tests, we are able to create a typical loading cycle on a test specimen to see how the number and magnitude of cycles affects the growth of cracks. After the test, we can analyze the fracture surface to see how…

Hill Engineering gave a presentation about fatigue analysis of pipelines at the 2018 Pipeline Pigging & Integrity Management (PPIM) Conference in Houston, TX. PPIM is the industry’s only forum devoted exclusively to pigging for maintenance and inspection, as well as pipeline integrity evaluation and repair. Hill Engineering’s presentation, titled “Is the Paris Fatigue Crack Growth…

Understanding residual stress is essential to predicting how manufactured components will perform in the real world. To help engineers and manufacturers better understand one of the industry’s most powerful measurement techniques, Hill Engineering has released a new video exploring the Contour Method for residual stress measurement in detail. The Contour Method provides a two-dimensional map…

Residual stress definition – residual stress is defined as the stress that is present in a material in the absence of externally applied loading. Residual stresses often form during manufacturing and are typically an unintentional byproduct of a manufacturing process. As engineers we care about residual stresses because they affect material performance. Because they are…

Later this year, RTX and Hill Engineering will each be hosting small groups of engineers from the other’s organization to provide experiential training courses to give additional insight into the work each does and the impact on engineered products. We look forward to meeting with everyone in the coming months. Below are short descriptions of…
