Abstract: This paper presents some results of a 3D numerical simulation model for level icestructure interaction. The method of solution uses the Wilkins’ (1973) finite-difference methodology and described by Jilenkov et al. (2002). The analyses in that paper showed that the Drucker-Prager failure criterion gives results close to a modified CoulombMohr criterion but needs less of computations because in this criterion we should not determine principle stresses in any point for each time step. This criterion is used in this paper. Some results of computations, namely velocity effect, stress distribution along the contact surface, problems of non-simultaneous failure are discussed.
