Case Study: Multi-step machining distortion modeling

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

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. Continue reading Face mask making with Hill Engineering

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
