How granular materials deform in quasistatic conditions
granular materials elastoplasticity stress-strain behavior
2010/11/19
Based on numerical simulations of quasistatic deformation of model granular materials, two rheological regimes are distinguished, according to whether macroscopic strains merely reflect microscopic ma...
Incremental response of granular materials: DEM results
discrete element simulation incremental behavior elastoplasticity flow rule hardening
2010/11/18
We systematically investigate the incremental response of various equilibrium states of dense 2D model granular materials, along the biaxial compression path (s11 s12 = 0). Stress increments are...
