PerSlipForestDislocationEvolution

Source: models/solid_mechanics/crystal_plasticity/PerSlipForestDislocationEvolution.py

Standard forest hardening model per slip system defined by \(\dot{\rho}_i = (k_1 \sqrt{\rho_i} - k_2 \rho_i) \left| \dot{\gamma}_i \right|\).

Inputs

dislocation_density — input · Scalar · required

Per-slip dislocation density

slip_rates — input · Scalar · required

Per-slip system slip rates

Outputs

dislocation_density_rate — output · Scalar · default dislocation_density_rate

Optional name for the derived output (defaults to ‘dislocation_density_rate’, i.e. the ‘dislocation_density’ variable name with the ‘_rate’ suffix).

Parameters

k1 — parameter · Scalar · required

Hardening coefficient

k2 — parameter · Scalar · required

Recovery coefficient
