PowerLawKinematicHardeningStaticRecovery

Source: models/solid_mechanics/plasticity/PowerLawKinematicHardeningStaticRecovery.py

This object defines kinematic hardening static recovery on a backstress term. This particular model uses a power law for recovery \(\dot{X} = - \left(\frac{\lVert X \rVert}{\tau}\right)^{n-1} \frac{X}{\tau}\) where \(n\) is the power law recovery exponent and \(\tau\) is the recovery rate.

Inputs

back_stress — input · SR2 · required

Back stress

Outputs

back_stress_rate — output · SR2 · default back_stress_rate

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

Parameters

tau — parameter · Scalar · required

Static recovery rate

n — parameter · Scalar · required

Static recovery exponent
