Hi, everyone!

I have read some literature to figure out how to set the parameters of JCFpmMat, especially the tensileStrength and the cohesion. However, I still have some problems.

The tensileStrength and cohesion parameters in [1] (t=16MPa, c=16MPa) and [2] (t=4.5MPa, c=45MPa) are different. 

I wonder that on what basis is the ratio of tensileStrength to cohesion set and how to set their value range? Why the parameters in the two papers differ widely?
