Explicit FE wrinkling simulation and method to catch critical bifurcation point in tube bending process YANG He(杨 合), LI Heng(李 恒), ZHAN Mei(詹 梅), GU Rui-jie(谷瑞杰) Department of Materials Forming...-walled tube NC bending process. In the study, a dynamic explicit FE model for aluminum alloy thin-walled tube NC bending process is developed to predict the wrinkling by using FE code ABAQUS/Explicit......
-walled Y-shaped tube was investigated. With axial feeding, tube material can be pushed into the die cavity to form a higher protrusion height with relatively small thinning ratio. For the Y-shaped tube, however, owing to the high-friction forces acting at internal pressure in the guiding zone between the tube and die, less metal flows into the protrusion. A multistage punch was proposed to change......
