AN INSIGHT INTO THE FAILURE OF REINFORCED SAND IN PLANE STRAIN COMPRESSION BY FEM SIMULATION

An FEM simulation of plane strain compression tests of dense Toyoura sand reinforced with reinforcement having a wide range of stiffness is described. Strain localisation is taken into account by modelling a shear band having a specific thickness and specific strain-softening properties determined based on experimental results. Global and local behaviour of the unreinforced and reinforced sand observed in plane strain compression tests are properly simulated.
