#HillEngSTEM Summer Challenge

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

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.

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

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

ASIP Conference 2019

Hill Engineering is presenting about residual stress aerospace forgings at the upcoming 2019 United States Air Force Structural Integrity Program Conference (ASIP) in San Antonio, TX. The 2019 ASIP Conference is specifically designed to bring together the world leaders in the area of aircraft structural integrity and to disseminate information on state-of-the-art technologies for aircraft structures in both the military and civilian fleets. Hill Engineering’s presentation will include a summary of recent work to quantify the residual stress variability in aerospace forgings. The abstract text is presented below.

Welcome Dallen Andrew

We would like to welcome Dallen Andrew to Hill Engineering. Dallen has 10 years of experience as a mechanical engineer supporting aircraft structural integrity programs. He received a BS degree in Mechanical Engineering from Utah State University in 2009, and a MS degree in Mechanical Engineering from the University of Utah in 2011.

During his career, Dallen has gained experience in many aspects of aircraft structural integrity, with specialization in the fatigue and fracture of metals. He has worked on many projects requiring him to utilize his capabilities in  fatigue crack growth analysis, fracture mechanics, durability and damage tolerance analysis (DADTA), fatigue testing, continuing damage, residual stress, finite element analysis (FEA), and non-destructive inspection.

Dallen is an organizer of the Engineered Residual Stress Implementation (ERSI) working group developing the analytical framework to allow the benefits from deep engineered residual stresses to be applied to aircraft inspection intervals for the United States Air Force. Dallen has significant experience supporting the A-10 and T-38 aircraft fleets. He also has significant expertise in the use of AFGROW and NASGRO fracture mechanics and damage tolerance software packages.

Please contact us today for additional information about Hill Engineering and the services we offer.

Engineered Residual Stress Implementation workshop

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 (September 12-13), 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.
