    Status: Open => Answered

Robert Caulk proposed the following answer:
Please reference line numbers like this [1] if you wish to solicit a
legitimate discussion. Next, it would be helpful if you tried to use the
correct geomechanical jargon. In this case "cohesive force" is ambiguous
since we do not know if you are referring to a force or a strength. It
seems you are not interested in the force, but instead the strength?
Strength in cohFrictPhys is defined by an adhesion [2], which has the
same units as the force. It is user defined. It is simply a criteria for
bond breakage; if the normal force [1] decreases below the user defined
adhesion, the bond breaks.
