Abstract: This study deals with a numerical simulation of the dynamic bending behavior of a floating icesheet subjected to the dynamic force by using ABAQUS/Explicit. The ice is considered as a homogeneous elastic material. An incompressible and inviscid of the flow is assumed. The fluid model is assumed to be a simple hydrodynamic model which is obtained by the equation of state material model which accounts for volumetric strength of hydrodynamic material. The pressure in the material is described as the function of density and bulk modulus. 2D and 3D fluidstructure interaction calculations are carried out. Infinite and semi-infinite floating ice-sheet is subjected to rapid loading at the ice edge. The displacement and stress distribution results acquired from FE calculation are compared with the analytical solutions. The FE results agree well with the analytical ones. Further, the influence of the dynamic response due to a rapid forcing and wedge angle is discussed. The large effect of free surface of water and the bending behavior depending on the ice wedge angles are demonstrated.
