Fracture Finite Element Analysis for Roll Forming of U Section Parts of TRIP 600 Steel

Abstract:

By applying the shear damage criteria, facture occurrence for roll forming of U Section parts of TRIP 600 steel is analyzed with nonlinear finite element. In accordance with the maximum value of steel sheet of plastic strains for the fracture initiation and with the application of the element deletion technology of the ductile fracture, the calculation of the damage evolution parameters of the material fracture is successfully set up. By applying the explicit dynamic solution method, the fracture finite element analysis of TRIP600U type section roll forming is realized, and the relationship among the stress, strain, energy density as well as damage evolution and material fracture is obtained.
