We recently uploaded a new case study on the topic of part distortion caused by residual stress during machining. We wanted to dive a little deeper into the topic with an analysis of a distorted aerospace part. Here is what we found. Continue reading Analysis of distorted aerospace part

Distortion of parts during the machining process is a significant problem faced by many machining vendors. This phenomenon typically results from the release and redistribution of residual stress in the material once the part is unclamped from the machine table. When not accounted for, machining distortion can lead to out-of-tolerance parts that either require reworking, or have to be scrapped. Continue reading Case Study: Multi-step machining distortion modeling
Summertime is just around the corner and we at Hill Engineering are always looking to engage our followers with fun and interesting information about engineering and residual stress. This summer we’re going to host the virtual Hill Engineering STEM challenge – a series of fun activities to demonstrate your engineering intuition and creativity. Participate on your own or with your family to compete for some cool Hill Engineering prizes! Continue reading #HillEngSTEM Summer Challenge
Staying safe and healthy during these times is something that’s on many people’s minds lately. Social distancing, washing our hands, and limiting outings are all things we can do to help “flatten the curve”. Wearing a face mask or covering when out in public is also something that can help protect others since some people with COVID-19 can show no symptoms. Face masks can be beneficial in areas with many people, since they can reduce the number of droplets we release when we speak, cough, or sneeze. Continue reading Face mask making with Hill Engineering
On your mark, get set, GO!
Hill Engineering isn’t just at the forefront of the residual stress measurement world, our employees are picking up the pace as well! The race pace that is. Today, we’re highlighting a few of our team members who cut through speed and strength like a wire EDM. Continue reading Racers of Hill Engineering
Our latest case study discusses our Broad Application for Modeling Failure (BAMF) software.
Broad Application for Modeling Failure (BAMF) enables fatigue crack growth analysis of parts with non-standard geometry, loading, and residual stress conditions through the implementation of multi-point fracture mechanics (MPFM). This user-friendly software environment provides structural analysts and engineers a tool to accurately and efficiently complete challenging fatigue crack growth problems.
Hill Engineering and Engineering Software Research and Development, Inc. (ESRD) have executed a joint marketing agreement to collaboratively promote the combined use of our software tools: Broad Application for Modeling Failure (BAMF) and StressCheck® for fatigue analysis. Continue reading Announcing Hill Engineering and ESRD agreement for joint BAMF/StressCheck marketing
Hill Engineering will be presenting at the upcoming Propulsion Safety & Sustainment Conference (PS&S) in Denver, CO on April 20th through April 23rd. We invite you to come see us. The mission of this conference is to proactively address or prevent problems with safety, readiness, reliability and sustainment within the tri-service turbine engine fleet, through the transition of existing and emerging technologies. Hill Engineering’s presentation will include a summary of recent work related to predicting residual stress and airfoil distortion from shot peening and laser shock peening. The abstract text is presented below. Continue reading Propulsion Safety & Sustainment Conference 2020
We’re putting something in a bottle, and no, it’s not an SOS to the world. It’s a strain gage!
Hill Engineering has recently developed technology to orient and apply strain gages inside a pressure vessel with restricted interior access. Continue reading Strain gage in a bottle
