Micropolar hypoplasticity for persistent shear band in heterogeneous granular materials
Finite elements Heterogeneity Hypoplasticity Micropolar theory Persistent shear band

Persistent shear bands in heterogeneous materials develop progressively, rather than instantaneously. For a meaningful capture of this deformation pattern, the band must develop naturally and freely u...

In the paper a simple fracturing model is presented using the 2D discrete element method capable of simulating large-scale brittle fracturing. It uses the combined MohrCoulomb and Rankine material mod...
