abstract = "A three dimensional constitutive model based on micromechanical behaviour of granular and columnar ice in the brittle regime is proposed. The model exploits the experimentally observed crack initiation mechanism; grain boundary sliding. The growth of the initiated cracks is assumed to follow the sliding wing crack approach. The model predicts qualitatively and quantitatively the major failure modes and strength of columnar and granular ice under biaxial compression. As shown in the numerical examples, the model captures for example the anisotropic strength of columnar ice under biaxial loading both across and along column loading. Although the model is able to predict splitting and spalling of columnar ice, the shear-like fault is not captured by the current model. The model is implemented into the Abaqus/Explicit FE-software.",
