CrystalPlasticityStrainPredictor

Source: models/solid_mechanics/crystal_plasticity/CrystalPlasticityStrainPredictor.py

Warm-up predictor for crystal plasticity models. Computes an initial guess for the elastic strain as \(\varepsilon^e = s \cdot \Delta t \cdot d\) where \(\Delta t = t - t_n\) is the time increment, \(d\) is the deformation rate, and \(s\) is a scale factor.

Inputs

deformation_rate — input · SR2 · required

Deformation rate

time — input · Scalar · default t

Time

Outputs

elastic_strain — output · SR2 · required

Predicted elastic strain

Parameters

scale — parameter · Scalar · default 1.0

Scale factor applied to the strain increment

threshold — parameter · Scalar · default 1e-3

Only apply the predictor if the old elastic strain norm is below this threshold.
