The Hoek-Brown-PAC model provides a representation for yielding that accounts for the changing failure condition. The BEM (boundary element model) Hoek E, Brown ET (1997) Practical estimates of rock mass strength. This model is derived directly from the Mohr-Coulomb model, and, like the Mohr-Coulomb model, can be used to perform factor of safety calculations using the model factor-of-safety command.
