v6.08.107 SSND107: Tractions, multiple rotations in large deformations, kinematic and mixed work hardening

Summary:

This test models an element subjected to four traction-rotation cycles of rigid bodies of \(45°\), with the laws of elasto-plastic behavior with kinematic and mixed work hardening in large hypoelastic deformations (GDEF_LOG). On the one hand, we check the invariance of the equivalent von Mises stress during the rotation phases, and that the values obtained with the various laws of behavior are identical. This test validates the kinematic work hardening treatment done in the context of large hypoelastic deformations.
