Bending stiffness EI, which is defined as cube of a material thickness, corresponds to the resistance to cross-sectional deformation. Thin Film materials have an extremely small bending stiffness because of a small second moment of area. Therefore, thin films deform nonlinearity and it is not easy to treat surrounding vortex structures. These flow fields around a moving thin body is treated as Fluid-Structure Interaction (FSI), and these phenomena have been continued a series of moving elastic deformation of the body, vortex generation, growing and development. In this paper, we simulate the fluid structure interaction simulation of flow field around an elastic thin film using ANSYS 12.1/ANSYS CFX 12.1. The purpose of this study is to clarify the effect of bending stiffness to the elastic deformation and the vortex flow structure of elastic thin films.
