Hello William,

Please read this paper:

https://www.sciencedirect.com/science/article/pii/S0022509612002268

There is a section (4) where a calibration procedure is proposed.
Careful, there is typo in table 3 where the C value for the granite
should be equal to 160 MPa and not 1600 MPa.

Basically, the tensile strength T and cohesion C values have to defined
in relation withe the degree of interlocking (coordination number /
interaction radius). From my experience, with the right coordination
number, the C/T ratio of the BPM can be defined equal to the ratio
compressive strength / tensile strength of the rock you want to model.

Luc
