- 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, \(\theta_{\text{melt}}\), is defined via the `MELTING TEMPERATURE` command line.

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

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