Abstract: The force exerted on a fixed offshore structure by impingement of ice sheet consists of several components - one to break the ice sheet, another of ride-up of broken ice pieces on the structure surface, another to move aside broken ice pieces, and so forth. Although the force to break ice sheet is not as big as the other components, the analysis of ice breaking pattern is important because the other components entirely depend on the shape and size of broken ice pieces. A new numerical model named 'Rigid Body Spring Model' (RBSM) has been adopted to analyze the bending failure problem of an ice sheet. A computer code has been developed and good agreement was obtained between the theoretically predicted values and the experimental ones.
