Abstract
Tapered FRP tubes have high energy absorption performance under axial compressive load. FRP will be useful for structural material of a shock absorber in the various industries. And in order to evaluate the behavior of this material, several experimental tests and numerical simulations using FEM are carried out recently. However, it is difficult to simulate the crushing behavior of tapered FRP tubes, so called “Progressive Crushing” with FEM, because the crushing mechanism contains various kinds of fractures such as delamination, fiber fracture and so on. In this study, we proposed a special purpose FEM based on experimental data that is useful for the crush-worthiness analysis of FRP tube.
