ERSI Workshop 2019 + WashU Racing Team Sponsorship
ESRD Co-Presents at ERSI Workshop 2019
ESRD’s Dr. Ricardo Actis attended and co-presented with technology partner Analytical Processes/Engineered Solutions (AP/ES) at the Engineered Residual Stress Implementation (ERSI) Workshop 2019 in Clearfield, UT. This annual workshop is focused on the development of a damage tolerance methodologies for fatigue crack growth through deep Engineered Residual Stress (ERS) fields.
Sponsored by the US Air Force’s A-10 Airframe Structural Integrity Program (ASIP), the goal of this workshop is to develop a roadmap for the implementation of the beneficial effect of engineered residual stresses within the United States Air Force (USAF) Damage Tolerance Analysis (DTA) fatigue crack growth and lifing programs.
At ERSI Workshop 2019, Dr. Thomas Mills (AP/ES) and Dr. Ricardo Actis (ESRD) co-presented “Fatigue Life Modeling at CX and Interference Holes”. The presentation summary is as follows:
- Crack closure experimental observations and modeling.
- Continuation of previous year’s work.
- Residual stress redistribution at interference filled holes.
- Task evolved from USAF goals dictated at ERSI.
- Goal is to better understand interference fit fasteners and their interaction with residual stresses from cold-working (CX).

ESRD Sponsors the WashU Racing Team
Congratulations to the Washington University in St. Louis Racing Team on a successful season! It was a pleasure to sponsor the team as they improved their global standings in multiple events, and increased their team to over 50 members. Below is a signed image of the racing team members, as well as a letter of appreciation sent to the racing team sponsors:
We are pleased to have a positive impact on our local engineering community, and look forward to our continued sponsorship of the team!
