Load history effect on plastic collapse in a notched SUS304 piping subjected to combined tension and bending

Abstract

This study is concerned with evaluating effects of a load history on the plastic collapse load of stainless steel pipes with a notch subjected to combined tension and bending. The stress state of a plastic collapse point was assessed using a membrane stress and axial displacement chart as well as a bending stress and deflection angle chart. As a result, it has been found that a different load history affects the formation of the plastic region and also the position of the plastic collapse point.
