ESRD has posed a new FEA challenge problem in the October 2018 issue of NAFEMS Benchmark Magazine. Can you show that you solved it with sufficient accuracy?

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?

Dr. Szabó has produced a converged solution for the spring rates in our high-fidelity FEA software StressCheck Professional, and is requesting solutions from the engineering community on how they tackled the problem.  He will publish his solution after the submission deadline of February 1st, 2019.

The problem posed in NAFEMS Benchmark magazine is as follows:

You can download the geometry (in Parasolid or STEP format) from nafe.ms/puzzler. Do you think you have the “FEA Puzzler” solved? Submit your reply to challenge@nafems.org by February 1st, 2019.
