摘要:Determination of the force effect of ice formations on the marine structure is based on a model of interaction with the edge of the ice field. The development of a model of ice failure accounting for the results of studies of the failure mechanism of the ice field edge with the surface of the vertical shape structure is presented. The processes of cracking and shear of different nature with the formation of large and small fragments are described with mathematical model. A criterion of the limit value of the accumulated potential energy of elastic compression of the ice volume before structure is proposed as specific energy of mechanical failure of sea ice. The values of this criterion, which takes into account all types of ice failure, are obtained experimentally by testing large samples of ice on dynamic crushing.
