Development of New Hybrid Shell Element takinging the Normal Stress into Account

摘要：

　　The calculation of the stress distribution in the forming stage of sheet metal forming is critical to the accuracy of springback simulation.In order to improve the accuracy of stress prediction,a new mixed shell element is presented.Two pseudo nodes are added in the thickness direction so that the normal strain can be calculated using the displacements of the nodes.Mixed formulation is used instead of that of pure displacement.As a result,the accuracy of stress prediction is improved.Examples are given to show the improvement.
