I have a question, I am comparing the 2d and 3d simulations for the results. For the cut sample / notched sample both 2D and 3D are matching (both are full-scale models), however, with uncut/un-notched sample the 2D and 3D results are not matching.
I am using the 2D geometry in the workbench and specifying the thickness for plane stress as 1mm.
If I change thickness to 1.5 for un-notched, the results will match. I am not able to understand why the mis-match is happening between 3D and 2D plane stress models for 1mm thickness.
