The unified rock mass elasto-plastic material model is implemented in ABAQUS user interface.
The Hoek-Brown rock mass criterion fits well with a large number of experimental data from intact rock materials to jointed rock mass.
According to the elasto-plastic theory, the incremental material matrix could be obtained as follows
