LinearIsotropicElasticJ2TrialStressUpdate

Source: models/solid_mechanics/plasticity/LinearIsotropicElasticJ2TrialStressUpdate.py

Update the trial stress under the assumptions of J2 plasticity and isotropic linear elasticity.

This allows the construction of fully scalar return mapping models for isotropic materials.

Inputs

elastic_trial_stress — input · Scalar · required

Initial trial stress assuming a purely elastic step

equivalent_plastic_strain — input · Scalar · required

Current guess for the equivalent plastic strain

Outputs

updated_trial_stress — output · Scalar · required

Trial stress corrected for the current increment of plastic deformation

Other options

coefficients — list · required

Coefficients used to define the elasticity tensor

coefficient_types — list · required

Types for each parameter, options are: INVALID, P_WAVE_MODULUS, POISSONS_RATIO, YOUNGS_MODULUS, SHEAR_MODULUS, BULK_MODULUS, LAME_LAMBDA
