Finite Element Simulation and Experimental Verification of Hydropiercing-Bend Process
In recent years, hydropiercing technique has been used widely. In this work, its special type of hydropiercing-bend is simulated using Rice and Tracey ductile criterion based on VUMAT of ABAQUS/Explicit and verified by experiments. Hydropiercing-bend processes with different slope angles of chamfer are discussed to predict the ultimate quality. It is shown that the angle of chamfer should be less than 70º for this kind of material and technical condition in order to make the slug attached with the tube blank.
