Abstract

Abstract: In order to simplify the structural integrity assessment of double cracked stainless steel piping, plastic collapse stress of asymmetric double notched pipes subjected to combined tension and bending was investigated. The experimental plastic collapse stress of the asymmetric double notched pipe is compared with the theoretical plastic collapse stress of the single notched pipe. The experimental plastic collapse points were over the theoretical collapse limit curve. The integrity of asymmetric double cracked stainless steel pipes subjected to combined tension and bending can be evaluated simply and conservatively using the theoretical plastic collapse stress of the single notched pipe.
