The Jointed Rock material model is contained in the Geomechanical Toolbox data item. This property supports Static Structural and Transient Structural analyses. For additional information, see Jointed Rock in the Material Reference.
The Jointed Rock property includes the following physical properties:
Residual Strength Coupling
Yield Surface
Initial Inner Friction Angle (Degree)
Initial Cohesion (Force/length2)
Dilatancy Angle (Degree)
Residual Inner Friction Angle (Degree)
Residual Cohesion (Force/length2)
In addition, once you insert the Jointed Rock model, the Jointed Rock - Additional Data data item displays in the Toolbox so that you can add one of the following:
Tension Rankine Yield Surface
Failure Plane Data Set
