v6.08.106 SSND106: Tractions, multiple rotations in large deformations, isotropic work hardening

Summary:

This test models a material point subjected to four rigid body traction-rotation cycles of \(45°\), with a Von Mises elasto-plastic behavior law with isotropic work hardening in large deformations (formulation with logarithmic deformation GDEF_LOG). We check on the one hand the invariance of the equivalent Von Mises stress during the rotation phases, and on the other hand its values during the tractions by comparing with the modeling of SIMO_MIEHE.

Models \(A\) and \(B\) deal with the problem in plane deformations, either in 3D (\(A\)), or in D_ PLAN (\(B\)).

Models \(C\) and \(D\) deal with the problem in plane constraints, either in 3D (\(C\)), or in C_ PLAN (\(D\)).
