Soft granular materials are assemblies of highly deformable grains interacting via surface forces. The large grain deformations these differ them from hard systems, in which, their behaviors essentially governed by rearrangements. In this paper, we study the uniaxial compression soft using a numerical approach based on Material Point Method allowing for deformations, coupled with Contact Dynami...

DEM-simulated model cohesive assemblies of spherical grains diameter d , with contact tensile strength F 0 once prepared in loose states, are quasistatically subjected to growing isotropic pressure P and then triaxial compression, maintaining lateral stresses ? 2 = 3 while increasing axial stress 1 + q strain ? . Reduced * P/ varies from 0.1 (cohesion dominated case, for which systems typically...
