Jérôme Duriez proposed the following answer:
Hi,
I've never used ViscElMat myself but the name, corresponding to a visco-
elastic behavior as explained in the doc [1], does not suggest it
includes cohesion..
Indeed, tensile interactions are not possible within this model [2,3],
and the maximum shear force is defined by a Coulombian threshold [4],
without any cohesion in shear as well
