Abstract: A pseudo-discrete continuum model was developed to study the breakage of the initial rubble skeleton. A special program was developed to generate a random assembly of rectangular blocks in a closed shape allowing to vary the block size and the resulting porosity of the assembly. The obtained assemblies were further used as geometrical input for the finite element model. The blocks were modelled as elasto-plastic bodies, contact elements were used to simulate the reduced strength at contacts between the blocks. Direct shear test simulation on the ice rubble were performed. The effect of the mechanical properties of the ice blocks and their contacts was investigated by applying different boundary conditions to assembly of the blocks.
