Analysis on Stress Distribution and Plastic Limit Load of Elbows in Gas Pipeline

MA Yehu

Abstract

The state of steel elbows in gas pipeline under internal pressure is analyzed with finite element analysis software ANSYS,and the stress distribution of elbows under different internal pressures is obtained.The plastic limit load of elbows is achieved according to the internal pressure applied to the model and the maximum equivalent plastic strain.
