Bending stiffness EI, which is defined as cube of a material thickness, corresponds to the resistance to cross-sectional deformation. Hyperelastic materials, such as gel and rubber materials, have an extremely small bending stiffness because of small body stiffness. The hyperelastic materials deform nonlinearity and it is not easy to treat surrounding vortex structures. These flow fields around a moving elastic body is treated as a fluid-structure interaction (FSI), and these phenomena have been continued a series of moving body, elastic deformation, vortex generation, growing and development. In the present paper, we simulate the fluid structure interaction simulation of flow field around an elastic moving body using ANSYS/ANSYS CFX. The purpose of this study is to clarify the effect of bending stiffiiess to the elastic deformation, the vortex flow structure and dynamic forces of the elastic moving body.
