【Abstract】 This paper discusses the plastic limit load of elbows with local thinn ed area under internal pressure. Fnite element analysis (FEA) and experiments ha ve been used. By data fitting of FEA, an empirical formula of the limit load for elbows with local thinned area has been attained. Limit load tests are carried out to validate the proposed formula.更多还原
