- The isotropic hardening model for the flow stress hardening model is defined with the ``ISOTROPIC HARDENING MODEL`` command line.

- The function name of a user-defined isotropic hardening model is defined via the ``ISOTROPIC HARDENING FUNCTION`` command line.

- The optional rate multiplier for the flow stress hardening model is defined with the ``RATE MULTIPLIER`` command line.

- The optional temperature multiplier for the flow stress hardening model is defined via the ``TEMPERATURE MULTIPLIER`` command line.

- The function name of a user-defined temperature multiplier is defined with the ``TEMPERATURE MULTIPLIER FUNCTION`` command line.

- For a Johnson-Cook temperature multiplier, the melting temperature, :math:`\theta_{\text{melt}}`, is defined via the ``MELTING TEMPERATURE`` command line.

- For a Johnson-Cook temperature multiplier, the reference temperature, :math:`\theta_{\text{ref}}`, is defined via the ``REFERENCE TEMPERATURE`` command line.

- For a Johnson-Cook temperature multiplier, the temperature exponent, :math:`M`, is defined via the ``TEMPERATURE EXPONENT`` command line.
