The results for an analysis with MAT1 (Linear elastic only) card and another with MATS1 (Non Linear using TABLES1 card) subcase is showing the same results.
The load applied should make the part undergo plastic deformation when MATS1 is used but this is not observed in the results.

The mats1 card is used in the nonlinear subcase.
But the loadstep of your model is “linear static” ，you should change it to 'nlstat'.
@mramakri
Run NLSTAT analysis with MATS1 and compare linear static results.
MATS1 will be ignored when the analysis type is LINEAR.
Thank you
