Abstract: The finite element method has been proven to be a very good calculation method of ice forces. The stress field and appearing ice forces in a continuous ice field during ice crushing against structures of different shape can very easily be evaluated by the finite element method. A flat ice sheet is discretized by three dimensional isoparametric elements or by three dimensional isoparametric elements and infinite isoparametric elements, idater under ice can be taken into account as an elastic foundation by interface surface elements. Ice is supposed to behave visco-elasto-plastic and its material properties are supposed to be orthotropic. Tsai-Nu criterion is adopted in plastic analysis. The contact section between structure and ice field has been taken into account as free and stiff. The results have been compared with earlier ones.
