A New 3D Crack Simulation Method of High Pressure Rubber Hose Pipe

To study the variations in stress/strain field when the crack appears, a new technique to simulate 3D crack of High pressure rubber hose pipe based on singular element and birth-death element was proposed. A part-through crack for High pressure rubber hose pipe simulated by utilizing this method and stress distribution caused by crack were analyzed. Simulation results indicate that the method is correct, effective, and convenient for further research, especially suitable for comparative analysis on the stress distribution changes and the stress reliefs which are caused by crack.
