>1. I can't visualize broken interactions in this way. At the end of the
test, the interactions that showed >"isBroken" only make up about 5%

I noticed in JointedCohesiveFrictionalPM.cpp, that the "isBroken" flag
is only tripped for bonds that fail according to the shear failure
criteria (assuming neverErase=false). For interactions that fail
according to the tensile failure criteria, the isBroken flag is only
tripped if we use "neverErase =True".

This might explain why the isBroken != !isCohesive at the end of a
triaxial test on a fully cohesive specimen.

Luc, maybe you can comment on why this is?
