Detailed Description

Trigger element by a linear combination of simple shear and a pure shear perturbations.

The contribution of both perturbation is computed as the minimal energy barrier needed to reach a yield surface for the triggered element, see:

The perturbations are established as the displacement field needed to reach mechanical equilibrium when an eigen-stress is applied to the triggered element (assuming elasticity everywhere). To get the two perturbations a sinple shear and pure shear eigen-stress are applied.

The configuration, including the definition of elasticity is read from the input System.
