Abstract
von Karman's effective width theory is constructed on the assumption that thin plate of elastic-perfectly plastic solid is subjected to static buckling. We examined whether von Karman's effective width theory is applicable to design of crush absorption structure. As a result, cross section of the member becomes effective against axial crush with increasing crush speed. It is found that the design based on the conventional theory is provided enough evidence of safety, thus, optimized design criteria can be proposed.
