abstract="Focusing upon finding an optimum shape of crash box, which is one of the most important part of an automobile body to absorb impact energy at the time of a collision, for ensuring large energy absorption, the effect of introducing notch into a crash box on controlling plastic buckling behaviour was examined by three-dimensional finite element analyses. The influences of notch shape and arrangement on the deformation mode of a polygonal crash box was numerically examined and an optimum range of the dimensions of notch was quantitatively determined for ensuring stable buckling deformation. As a result, a fundamental scheme to optimise the shape and arrangement of the notches to ensure large energy absorption was proposed, which is applicable to a crash box with optional cross-sectional shape.<p />",
