Finite element analysis of the foam-filled bitubal circular tube under multi-impact loading

Abstract

Crush analysis of bitubal cylindrical tubes under different impact angles (0°, 10°, 20°, 30°) is described in this paper. Finite element analysis (FEA) was used to determine numerical solution of double cylindrical tubes. Moreover, mass block as impactor impacted the structure in longitudinal direction of the tubes. With variations of load angle and dimensions of tube, a model of structure was developed by non-linear FEA software. The parameters such as the peak cruising force (PCF), energy absorption (EA) and specific energy absorption (SEA) are the outcomes of this study, thus it can be expected that this tube is the great energy absorber.
