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.

“The p-type element has been used to great advantage in the finite element system ESRD StressCheck®, . This software provides the engineer with the means to conduct solution verification in an extremely straightforward manner by simply increasing the degree of the element, monitoring convergence and using Richardson extrapolation reliably to estimate the error. This can be conducted automatically by the software thereby enabling the engineer to concentrate on the engineering rather than the simulation. StressCheck® has also been used to develop ESRD’s Handbook and Toolbox applications. The first of these provides engineers with a repository of parameterised standard problems of the type found in texts like Roark’s “Formulas for Stress and Strain”, . The second, Toolbox, is a tool that can be used to parameterise a company’s range of components for rapid and reliable analysis by non-expert analysis. Toolbox then is an exemplary of the way in which the democratisation of simulation can be applied.”
