**process inelastic

Description

This post-processing computes the inelastic strain for a given Cauchy stress and an elasticity matrix which can depend on external parameters. Small strain conditions are assumed.

\[\ten \varepsilon^{in} = \tenf C^{-1}({\tt EP})\left(\tenf C({\tt EP}):\ten \varepsilon-\ten \sigma\right)\]

Syntax

**process inelastic \(~\,\) *stress stress \(~\,\) *strain strain \(~\,\) *elasticity <ELASTICITY> \(~\,\) *params ext_params

*stress stress

name of the input stress tensor.

*strain strain

name of the input total strain tensor.

*elasticity <ELASTICITY>

elasticity matrix.

*params ext_params

list of external parameters (temperature, …)

The output inelastic strain is named ein.
