Simulation and Analysis on Crack Propagation of Bimetallic Tube Based on ABAQUS

摘要

Based on ABAQUS finite element analysis software, metallurgical composite bimetallic tube containing crack is analyzed and obtained the process of pipe rupture and the internal change of Mises stress and displacement at different crack depths and loading conditions. As the crack depth increases, the minimum values of the pipe Mises stress will increase and the maximum remain unchanged; as the load increases, the Mises stress and displacement values inside the pipe will increase with the equal speed. Maximum are all generated near the crack tip.
