Results are presented of numerically simulated three dimensional quasi-static shear deformation of polydisperse systems of spheres. Results of axisymmetric compression test simulations are reported for both dense and loose systems. The versatility of numerical simulation is demonstrated by presenting results obtained from simulations of general radial deviatoric loading, a constant deviatoric strain test and a multi-axial plane strain test. In all cases, the simulated stress-strain dilation responses are in excellent qualitative agreement with the behaviour of granular materials observed in physical experiments.
