Abstract: Object and purpose of research. The object of research is marine engineering structures. The purpose is to assess the outlook for application of smooth particle hydrodynamics (SPH) for numerical modeling of ice loads. Materials and methods. For this purpose an overview of the most popular methods for numerical solution of problems in fracture mechanics is given with their merits and drawbacks (finite element method, extended finite element method, discrete element method, smooth particle hydrodynamics, smoothed particle Galerkin). Main SPH relations are presented. Main results. A test problem of a cylinder leg interacting with level ice field is used to obtain a qualitative pattern of ice deformation and failure with and without ice breaking arrangements, as well as under the global ice load. Conclusion. Analysis of obtained results shows that SPH in the sliding least square method formulation is promising for numerical modeling of plastic damage in fine grained ice and definition of corresponding loads on marine structures.
