Abstract

The authors investigate numerically stress-strain state of a granular material around a rigid circular inclusion in case of combined loading with continuous turn of shearing. Dilatancy, dry friction and viscosity are taken into account. It is shown that under certain conditions, the rigid inclusion undergoes the influence of a momentum of turn contrariwise the shearing. The numerical investigation results are compared with the relevant experiment data.
