We modelled punch through tests on partly consolidated ice rubble using 2D combined finite-discrete element method (FEM-DEM). We ran simulations with various freeze bond strengths and block to block friction coefficients. In this paper, we demonstrate the close relation of rubble failure and deformation patterns to indentor load records. We show that the buoyant load component due to the rubble becoming detached from the surrounding rubble field, and displacing during an experiment, is of crucial importance in interpretation of punch through test results in terms of ice rubble material properties.
