摘要：In this paper, the shell element with drilling degree of freedom (DOF) is applied to springback analysis, which possesses most satisfactory robustness and accuracy by describing complicated bending deformation precisely. At each node, six DOF make the element easy to connect to space beams or intersecting shells. The locking phenomena are controlled. We conducted implicit finite element method (FEM) analysis for springback simulation with this element in which the results show as good quality as BT shell, and in a few cases even better performance. As a result, this element is integrated in our stamping analysis software platform King Mesh Analysis System.
