Abstract

A ladder frame structure of a pickup truck absorbs most part of energy in frontal crash. The frame structure consists of thick steel plates, and to simulate buckling phenomena of the thick plates by using shell element is sometimes difficult. In this report, characteristic curves of force against displacement of the frame's parts under compression and bending load are evaluated by both shell and solid elements, and limitations of applying shell elements to simulate post-buckling phenomena such as effective width of the frame are discussed.
