YieldFunction

Source: models/solid_mechanics/plasticity/YieldFunction.py

Classical macroscale plasticity yield function, \(f = \bar{\sigma} - \sigma_y - h\), where \(\bar{\sigma}\) is the effective stress, \(\sigma_y\) is the yield stress, and \(h\) is the isotropic hardening (optional: omit the isotropic_hardening HIT option to drop the \(- h\) term entirely).
