FEM and springback analysis of DP980 steel roll forming based on different elements

Journal Article


Abstract


  • In this study, the conventional shell element and continuum shell element are used in the Finite Element Modeling (FEM) simulation of U-shaped roll forming process with DP980 steel sheet of 0.9 mm in thickness. Then the accurate springback analysis of the simulation result is established by the method of importing the explicit result to the implicit algorithm. By contrast with the experimental results, it shows that FEM simulation results with the continuum element have higher precision in shapes and dimensions. And the simulation results combined with the static springback method agree with the experimental results better, for the error of bending angle are merely 2.19% and 1.52%. So this will offer guidance and reference for the future research of roll forming process simulation.
