Bruno Chareyre proposed the following answer:
Hi Alexander,
Arguably, the documentation of Law2_ScGeom6D_CohFrictPhys_CohesionMoment is
short (did you read it [1]) but it actually answers your questions.
>how cohesion forse depends on destination [distance?] between particles
Exactly like in the non-cohesive model, linearly.
>formulas for cohesion and non-cohesion forces
there is no such distinction. There is a contact force, bounded by
values computed based on friction and/or cohesion parameters. The
details are in the doc.
>when cohesion bond breaks
It breaks when contact force exceeds the bounds mentionned above, by
definition.
You may check Bourrier2013 where some more equations are given.
Regards
Bruno
