Fluid-Structure Interaction Analysis of a Rubber Bellow Segment made of Hyper Elastic Material
Abstract: Fluid-structure interaction (FSI) is the interaction of a moveable and/or deformable structure that is immersed in a fluid and/or contains a fluid. Motion of the structure causes a change in the fluid’s stresses that act on the structure’s wetted surface, which in turn causes a change in the structure’s motion. The present research analyses the deformation produced in a hyper elastic rubber bellow segment due to the pressure generated by …
