The Inelastic Strain Rate subnode allows you to provide inelastic strain contributions to the material models Linear Elastic Material, Layered Linear Elastic Material, Nonlinear Elastic Material, or 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. For the Layered Linear Elastic Material, the inelastic contribution can be applied to arbitrary layers in a multilayered membrane when the Composite Materials Module is available.

See the documentation for the Inelastic Strain Rate node in the Layered Shell chapter.
