This paper investigates the crashing behaviour of thin-walled structures having various cross-sections subject of dynamic axial loading. The aim is to understand the collapse mode formation, energy absorption behaviour and progressive buckling phenomenon regarding TWB thin-walled structures. Three different cross-section shapes were used for this study as it follows: circular, hexagonal, rectangular. In the fabrication process of the structure itself, homogeneous materials are often used but an attractive solution for the automotive companies is materialized by the use of tailor welded blanks. In this paper, the impact crashing procedure was performed using a custom impact setup and the non-linear finite element platform LS-Dyna V4.0. After these analyses it can be concluded that a correlation between the number of folds and the mean load and the weld line could be made. The number of folds tends to increase as the mean load also increases. The weld line has an important role in the collapse mode formation and the values of the mean load.
