In a frontal collision of an automobile, side members are the most important factor in occupant protection. When the side members collapse axially, they absorb a sufficient amount of crash energy to avoid deformation of compartments. To promote axial collapse without bending, beads are generally provided on the side member. However, it is very difficult to determine the effective position for beading on the members because the relation between the buckling wave and the beads cannot be clearly seen in a bending crash mode. In this study, we show an analytical method of beading on the side members along the buckling mode calculated by a finite-element analysis.
