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

Face mask making with Hill Engineering

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.

Case Study highlight: Broad Application for Modeling Failure

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.

Propulsion Safety & Sustainment Conference 2020

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

HE Pet Spotlight: Delta

Delta, the dog.

In addition to residual stress, family pets are a special subject here at the office. This year at Hill Engineering, we’re starting a new blog series that highlights our four-legged friends. Don’t think that we forgot about animals with less than four legs, they’re coming up next! To kick things off, let’s meet Delta. Continue reading HE Pet Spotlight: Delta

Residual Stress 101 vlog

Today, we’ve released the newest episode of our vlog: Residual Stress 101. The video is a return to basics, discussing the core of what it is we do here at Hill Engineering.

If you haven’t checked out our YouTube channel, it might be time. Our mission is to post content that helps highlight the capabilities of our organization, so that everyone can see how and why residual stress is important to their manufacturing processes.

Today’s post is a broad overview of what residual stress is, including the several techniques for measuring residual stress found in our lab. Look for future content that delves further into each technique, and contact us if you have any further questions or want to see a video related to something we haven’t discussed.  

BAMF version 7.0 release

Following the inputs from our user community, we continue to develop new capability in the Broad Application for Modeling Failure (BAMF) software. We are happy to announce the new version of BAMF (7.0) is now available, which includes several significant enhancements that improve the usability of BAMF and adds to the state-of-the-art capability not available in other fatigue analysis tools.
