Abstract

This paper presents the numerical assessment of crushing responses of elliptical tubes under crushing forces. Based on the literature survey, tremendous amount of works on the axial crushing behavior can be found. However, the studies on the oblique crushing responses are rarely found, Therefore, this work investigates numerically the elliptical tubes under compressions. The numerical model of the tubes are developed suing ANSYS finite element program. Two important parameters are used such as elliptical ratios and oblique angles. The tubes are compressed quasi-statically and the force-displacement curves are extracted. Then, the area under the curves are calculated and it is represented the performances of energy absorptions. It is found numerically that the introductions of oblique angles during the crushing processes decrease the crushing performances. On the other hand, the elliptical-shaped tubes are capable to enhance the energy absorption capabilities.
