Abstract

The paper studies sheet metal forming process using finite element analysis for large elastic-plastic deformation, offering both theoretical and methodological contributions to the subject. Sheet bending process is simulated using finite element analysis software ANSYS. The springback phenomenon is examined in great details. Taking A3 sheet as a specimen, the analysis presents springback values in the bending process, as well as a curve of springback vs. relative bending radius R/t, curve of springback vs. bending clearance between punch and cavity, curve of springback vs. material response (stress-strain curve) during plastic deformation. The simulation results provide valuable information for die modification.
