Numerical approximation of plane deformation for the indentation of granular material by a smooth rigid wedge punch

In this paper, a numerical approximation of the stress equation for the indentation of granular materials by a smooth rigid wedge is presented. Plane strain conditions are assumed, and the materials obey the Mohr-Coulomb yield condition. This method determines the deformation of granular material un...
