AbstractA three-dimensional, time-dependent, elasto-plastic constitutive model for fresh water transversally isotropic columnar grained S-2 ice is presented in this paper. The model describes the stress?strain behaviour of ice subjected to any loading scenario, including cyclic loading. It takes into consideration the material non-linearity, time dependency, plasticity, material anisotropy, and hysteresis behaviour of ice when subjected to cyclic loading. It accounts for the effect of grain size, confining pressure, and micro-cracking on the mechanical behaviour of the material. The model can be implemented into an explicit dynamic finite element code, which can be used to compute impact loads exerted by ice on ships and offshore structures. The capability of the model to predict the results of laboratory tests is demonstrated. Comparisons between predicted and measured stress?strain curves are presented.
