Résumé	In this paper, an ice-sheet/water system is used to study the icebreaking pattern. Theory of elastic-wave propagation is utilized to deal with the following problem: an icebreaker moves forward and impinges on the edge of an ice-sheet which floats on calm water. As a consequence, elastic waves are generated at that edge of the ice-sheet, and propagate in all directions. The icebreaking process takes place in the ice-sheet when the ice-sheet absorbs a considerable amount of energy from the impact. In the meantime, the water underneath the ice-sheet is disturbed by the ice-sheet motion, and partially reacts on the ice-sheet. Elastic-wave profiles are obtained for normal and shear stresses. Based on those results, the ship icebreaking resistance can be computed from the dynamic fracture point of view.
