Finite Element Analysis and Fracture Forecast of U Channel Flexible Roll Forming

摘要：

　　Focus on fracture defect of DP980 in Flexible roll forming,this research have done a finite-element analysis based on explicit solver and shear damage criterion,and using element deletion of finite element software ABAQUS to realize the fracture evolution of sheet damaged area.During the modeling,parameters of fracture evolution are set,and finally gain the conclusion about the relationship between stress,strain,energy density and fracture.The research provides theoretical guidance for practical production.
