ComputeMultipleInelasticCosseratStress

under construction:Undocumented Class

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

  • inelastic_modelsThe material objects to use to calculate stress and inelastic strains. Note: specify creep models first and plasticity models second.

    C++ Type:std::vector

    Options:

    Description:The material objects to use to calculate stress and inelastic strains. Note: specify creep models first and plasticity models second.

Required Parameters
