Abstract
Crashworthiness is an important criterion in vehicle design. In fact, a crashworthy design will reduce the terrible accidents that happen everyday. Normally, tube structures are used for this task by dissipating the impact energy on the folding waves formed during the crushing progress. This study continues the previous studies, focuses on analyzing the behavior of tubular-hat subjected to axial collision. Because of the limitations on the experimental conditions, and by the finite element method, this study only concentrates on the tube section. There are two main objectives in this thesis. Firstly, we consider the difference between the behaviors of the top-hat tube and of the double-hat tube with the same axial load. Then, the geometric influence of flange on the deformation of the tubular-hat is investigated.
