Abstract

Abstract

The paper discusses the plastic limit pressure of elbows with local thinned area on inner wall of extrados. In this research, finite element analysis (FEA) has been used. The results of FEA show that the plastic limit pressure of the elbow with local thinned area on inner wall of extrados are slightly lower than the one of the corresponding elbow with local thinned area on outer wall of extrados. By data fitting of FEA, an empirical formula of the limit pressure for elbows with local thinned area on inner wall of extrados has been attained.
