Solve the model applying the Hoek & Brown failure criteria

SOLUTION : GEOTECHNICAL MODULE: Hoek & Brown

Notes

-  This command solves the model changing the material properties of the rocks defined in CivilFEM to adapt them to the Hoek & Brown failure criteria. These changes imply the adjustment of some parameters (cohesion, friction angle and the dilatancy) to the existent stress state. There are two types of analysis that can be carried out with this command:

-          Between substeps: The program changes the material properties in each substep of the Newton-Raphson non-linear process.

-          Between solves: The program carries out the first ANSYS solve and changes the material properties according to this stress state.

-  These two calculation options are controlled using the command ~CFCONFG (~CFCONFG,HB,HBSOL,TYPE) where TYPE equal to 0 (default value) means the resolution between solves and TYPE equal to 1 sets up the resolution between substeps.

-  The non-linear analysis options and the convergence control are ANSYS parameters; therefore the corresponding ANSYS commands should be used to set up them. 

-  This commands automatically activates the plastic stresses and strains writing (ANSYS OUTRES command) to be able to read the resultant stresses.

-  Additionally, it’s possible to tell the program to only modify the material properties of those elements previously stored into a component called HBCHANGE.
