차체구조용 박육부재의 압궤특성에 관한 연구

In this paper, collapse test of thin-walled structural member widely used for automobiles is carried out under static compression load to observe the effects of cross-sectional shape and material on the energy absorbing capacity in the viewpoint of crashworthiness. Specimens tested consist of two sorts C Aluminium, CFRP) and configurations C Circular, Square) with variation in thickness. Also, comparisons of Al circular and square specimens are made to find the influence of difference in shape on the energy absorbing capability according as the thickness of specimen varies.
