本文采用更新式拉格朗日描述,建立了基于连续介质力学的非退化四节壳单元有限元模型,使用自行开发的基于上述模型的有限元程序对杯形件的拉深过程进行了数值模拟,并与实验结果进行了比较。
In this paper, we use the updated Lagrange description to establish a finite element model of non-degenerate four-shell element based on continuum mechanics. The finite element program based on the above model is used to simulate the drawing process of cup element. , And compared with the experimental results.
