# ComputeMultipleInelasticCosseratStress

The ComputeMultipleInelasticCosseratStress has not been documented, if you would like to contribute to MOOSE by writing documentation, please see Documenting MOOSE. The content contained on this page explains the typical documentation associated with a MooseObject; however, what is contained is ultimately determined by what is necessary to make the documentation clear for users.

Compute state (stress and other quantities such as plastic strains and internal parameters) using an iterative process, as well as Cosserat versions of these quantities. Only elasticity is currently implemented for the Cosserat versions.Combinations of creep models and plastic models may be used

## Input Parameters

- computeTrueWhen false, MOOSE will not call compute methods on this material. The user must call computeProperties() after retrieving the Material via MaterialPropertyInterface::getMaterial(). Non-computed Materials are not sorted for dependencies.
Default:True

C++ Type:bool

Description:When false, MOOSE will not call compute methods on this material. The user must call computeProperties() after retrieving the Material via MaterialPropertyInterface::getMaterial(). Non-computed Materials are not sorted for dependencies.

- tangent_operatornonlinearType of tangent operator to return. 'elastic': return the elasticity tensor. 'nonlinear': return the full, general consistent tangent operator.
Default:nonlinear

C++ Type:MooseEnum

Description:Type of tangent operator to return. 'elastic': return the elasticity tensor. 'nonlinear': return the full, general consistent tangent operator.
