Energy Absorption Capacity of Expanding Tube with Fiber-Reinforcement
Abstract. This contribution presents the investigation of energy absorption mechanism of metal tubes and composite-wrapped metal tubes subjected to a diametric deformation via an expansion process. In the experiments, the expansion of the tubes was performed under quasi-static loading using a conical-cylindrical expansion die. The experimental results are repeatable and thus reliable. An extensive finite element analyses and experimental investigation were carried out in parallel. Both two-dimensional and three-dimensional finite element models were created based on the actual experimental geometrical and material parameters. Results from the finite element analyses correlate rather well with the experimental data. Glass fibre-wrapped metal tubes showed an increased steady-state reaction force which in turn reflects better specific energy absorption capacity for every layer of composite wrapped as compared to bare metal tubes.
