SlopeSaturationVoce isotropic hardening model, \(\dot{h} = \theta_0 \left(1 - \frac{h}{R} \right) \varepsilon_p\), where \(R\) is the isotropic hardening upon saturation, and \(\theta_0\) is the initial hardening rate. In addition to the reparameterization, this model differences from the VoceIsotropicHardening model in that it defines the hardening rate in a non-assocative manner. This is sometimes handy, for example in supplementing the model with static recovery.
