WebFEA of Stress Concentrations So I'm making a few case studies here and there and struggled in matching the experimental SCF results to my FE model and they either overpredict or underpredict. Is there any wrong with my FE model? Or is an innate limitation of the Linear Static Structural Analysis? WebFeb 23, 2006 · If your FEA is showing you a maximum stress of 40ksi in your part and 30ksi of it is in a single element at your stress concentration, then you can either refine the mesh to see what happens to the results, perform a non-linear analysis (probably not warranted until you've tried the mesh refinement), or ignore those highly localized results.
