Mechanics of ice–structure interaction

The physical processes involved in the interaction of ice masses with offshore structures are described. For design purposes, two pressure-area relationships have been deduced, which take into account the randomness of data. The first is for local pressures, using ranked data from ship rams, resulting in a power-law decrease (≃−0.7) of pressure with design area. A second (global) pressure-area relationship with random parameters has been...
