ESRD’s Dr. Ricardo Actis attended and presented with technology partner Analytical Processes/Engineered Solutions (AP/ES) at the Engineered Residual Stress Implementation (ERSI) Workshop 2019 in Clearfield, UT. The goal of this annual workshop is to develop a roadmap for the implementation of the beneficial effect of engineered residual stresses in damage tolerance analysis (DTA).

Also, ESRD would like to extend our sincerest congratulations to the Washington University St. Louis racing team, who we sponsored this past year to improvements in multiple events, including engineering design. Great job, team!

In NAFEMS’ July 2019 edition of Benchmark Magazine, ESRD Chairman Dr. Barna Szabó reveals the converged StressCheck^® solution for the incremental spring rates, provides a summary of the FEA Puzzler respondent submissions, and documents the various approaches taken by the respondents.

The deadline for the NAFEMS coil spring “FEA Puzzler” submissions has been extended through June 1st! View a teaser video of ESRD’s StressCheck^® model and qualitative deformation results.

In the October 2018 issue of NAFEMS Benchmark magazine, ESRD Chairman Dr. Barna Szabó posed a new “FEA Puzzler”: Can you determine the progression in spring rate as a 3D coil spring is deformed? And, can you verify the accuracy of your solution? Give it your best shot!

ESRD’s Dr. Ricardo Actis attended and presented with technology partner Analytical Processes/Engineered Solutions (AP/ES) at the Engineered Residual Stress Implementation (ERSI) Workshop 2018 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.

In recent years, Digital Engineering contributor, NAFEMS instructor and FETraining.net developer Tony Abbey has put together a list of practical engineering simulation case studies, walk-thrus and software overviews for a variety of FEA software tools.

Watch as ESRD reproduces a selected set of his 3D detailed stress analysis case studies, and see how we compare with Digital Engineering’s published results!

This past year, ESRD’s Drs. Barna Szabó and Ricardo Actis collaborated with NAVAIR’s Mr. Dave Rusk on a technical paper titled “Fatigue Life Prediction of Flaw-Tolerant Damaged Rotorcraft Structures”.  This paper was presented at the American Helicopter Society Annual Forum 74 in Phoenix, Arizona May 14-17, 2018.
