Abstract

By using the results of numerical simulations, we show that particle rotations and contact couples influence the shear strength and the localized failure modes of idealized granular materials. In the absence of contact couples, the overall friction angle is smaller than the interparticle friction angle, as a result of the concentration of particle rotations within shear bands. In the presence of large contact couples (without particle rotations), the overall friction angle becomes larger than the interparticle friction angle and the deformation localizes in failure patterns different from those observed experimentally in granular media.
