Shear Bands with Dilatancy modelled with Underworld

Louis Moresi

Abstract

In honour of Hans Mühlhaus' 70th birthday this month, here are some shear band simulations made with Underworld. We are investigating the role of dilatancy in the geometry of the shear bands for a box of material when a small trapdoor is opened. The extent to which large-scale deformation is needed to release material through the trapdoor depends on how much the material dilates when shear bands form.
