Introduction
Stresses and displacements are determined numerically for the case of a cylindrical hole in an infinite Mohr-Coulomb material subjected to an isotropic in situ stress field. The analytical solution for this problem is provided by Salençon (1969) for associated and non-associated plastic flow. The problem tests the Mohr-Coulomb model with applied field stresses in plane-strain conditions imposed in SIGMA/W.
