Detailed Description

ComputeMultipleInelasticStress computes the stress, the consistent tangent operator (or an approximation to it), and a decomposition of the strain into elastic and inelastic parts.

By default finite strains are assumed.

Cosserat couple-stress, and the cosserat version of the consistent tangent operator are also computed, but only using Cosserat elasticity.

The elastic strain is calculated by subtracting the computed inelastic strain increment tensor from the mechanical strain tensor. Mechanical strain is considered as the sum of the elastic and inelastic (plastic, creep, ect) strains.

This material is used to call the recompute iterative materials of a number of specified inelastic models that inherit from StressUpdateBase. It iterates over the specified inelastic models until the change in stress is within a user-specified tolerance, in order to produce the stress, the consistent tangent operator and the elastic and inelastic strains for the time increment.

The current Cosserat models do not know they might be using the "host" version of the elasticity tensor during the return-map process.

Therefore, they compute the incorrect elastic/inelastic strain decomposition. Overriding this method allows the correction to be made.

void ComputeMultipleInelasticStress::updateQpState	(	RankTwoTensor &	elastic_strain_increment,

overrideprotectedvirtualinherited

Given the _strain_increment[_qp], iterate over all of the user-specified recompute materials in order to find an admissible stress (which is placed into _stress[_qp]) and set of inelastic strains, as well as the tangent operator (which is placed into _Jacobian_mult[_qp]).

Parameters

elastic_strain_increment	The elastic part of _strain_increment[_qp] after the iterative process has converged
combined_inelastic_strain_increment	The inelastic part of _strain_increment[_qp] after the iterative process has converged. This is a weighted sum of all the inelastic strains computed by all the plastic models during the Picard iterative scheme. The weights are dictated by the user using _inelastic_weights
