In article for description of rheology of limnetic polycrystalline ice the model of an elasto-plastic material with an isotropic hardening and von Mises yield condition is accepted. For modelling creeping this material can be used without failure criterion. For modelling failure the hydrodynamic model of behaviour of the failure elements is offered. For a saving of time of calculation in CAE systems without essential lost accurasy the criterion of removal of the failure elements, a representing limiting relative integration step is offered.
