Abstract
Judging from the mechanical properties of ice sheet, ice sheet is an elastic-plastic substance, and in high strain region, it is seemed as elastic material. Generally ice load acting on structures and mechanisms of its fracture mode depend on the strain and stress rate. In the case of large moving ice sheet colliding with structure, the decision of deformation area of ice sheet was very difficult. In this paper, therefore the authors clarified the deformation area of ice sheet which collides with pile structures at high speed.
