v6.03.107 SSNP107 - Traction-shear plate: Lemaître viscoelasticity and isotropic work hardening

Summary:

This nonlinear quasistatic mechanical test consists in loading a square plate under tension-shear load. The sequence of several calculations is thus validated with alternately a law of plastic behavior with isotropic work hardening and a law of viscoelastic behavior of Lemaître, the value of the internal variables (cumulative plastic deformation) and charge indicator (discharge) at the end of one calculation being repeated at the beginning of the following calculation. The load remains radial throughout the test.

The plate is modelled by a volume element (HEXA8).
