Plastic Collapse of Thin-Walled Beams

Abstract

This paper describes the characteristics about the plastic collapse of thin-walled beams subjected to dynamic load. The basic equation of the visco-plastic constitutive relation was shown for the local buckling on the thin-walled members. The static function is necessary because visco-plastic term depend on the over-stress which is difference of dynamic and static stress. The expression of the function and experiments for static collapse for thin-walled members are studied.
