1. Reference problem#

1.1. Geometry#

We consider a unit cube.

1.2. Material properties#

We consider a material with a Von Mises law of behavior with mixed work hardening (VMIS_ECMI_TRAC).

The elastic properties are as follows:

  • Young’s modulus: \(E=221300\mathrm{MPa}\)

  • Poisson’s ratio: \(\nu =\mathrm{0,3}\)

The Prager constant is: \(C=2200\mathrm{MPa}\).

The traction curve under consideration is given on the.

1.3. Boundary conditions and loads#

The underside (in plane \(z=0\)) is embedded.

The upper face (in plane \(z=1\)) is subject to a vertical movement \(\mathrm{dz}={10}^{-2}[m]\).
