The Inelastic Strain Rate subnode allows you to provide inelastic strain contributions to the material models
Linear Elastic Material,
Nonlinear Elastic Material, and
Hyperelastic Material on a variety of formats as in
External Strain. Here, however, the inelastic contribution is given as a rate, and the total inelastic contribution is computed by integrating this rate in time.
If the same layer is selected in two Inelastic Strain Rate nodes being active on the same boundary, the contributions will be added.
