In RocData, you can choose to work with one of the following strength criteria:
To choose a strength criterion, select Project
Settings from the toolbar or the Analysis
menu, and select one of the four options. The default strength criterion
in RocData is Generalized Hoek-Brown.
When a strength criterion is chosen, all input and output data will pertain to the selected criterion. However, equivalent Mohr-Coulomb parameters are always calculated, if you have selected one of the non-linear strength criteria (Generalized Hoek-Brown, Barton-Bandis or Power Curve).
The following table summarizes the range of applicability for each strength criterion.
