1. Reference problem#

1.1. Geometry#

It is a material point: a state of homogeneous stresses and deformations. This can be represented by a single finite element, with appropriate boundary conditions, as in SSNP14 and SSNP15.

1.2. Boundary conditions and loads#

A loading path defined by a tensile component and a shear component is imposed, in the following manner:

1.3. Material properties#

The behavior is Von Mises elastoplastic, with isotropic work hardening. Work hardening is linear.
