In the Geotechnical Analysis add-on, the Hoek-Brown material model is available. The model shows linear-elastic ideal-plastic material behavior. Its nonlinear strength criterion is the most common failure criterion for stone and rocks.
You can enter the material parameters using
- Rock parameters directly, or alternatively via
- GSI classification.
You can find more information about this material model and the definition of the input in RFEM in the corresponding chapter of the online manual for the Geotechnical Analysis add-on: Hoek-Brown Model .
