Abstract
In this paper, crushing force and energy absorption of foam-filled conical tubes with fiber reinforced layer between two metal walls under axial loading have been studied by means of an analytical method. Based on the axially crushing models, a simplified analytical solution for the static crushing of foam-filled fiber reinforced conical tubes is presented. The influences of fiber reinforced orientation, fiber layer thickness and base angle of conical tube on energy absorption capability were studied in examples. A validated finite element method was introduced to simulate the collapse of foam filled metal conical tubes and indirectly verified the feasibility of the simplified analytical model proposed in this paper.
