基于弹塑性环形板的二维屈曲模型和著名的能量法，得到了圆毛坯凸缘在拉深过程中弹性屈曲和塑性屈曲的临界条件，以改进先前给出的结果[1, 4]。压边圈对屈曲和产生的波数的影响也可以定量预测。
Based on a two-dimensional buckling model of an elastic-plastic annular plate and the well-known energy method, the critical conditions for the elastic buckling and the plastic buckling of the flange of a circular blank during the deep-drawing process are obtained to improve upon previously given results[1, 4]. The influence of a blankholder upon buckling and on the number of waves generated can also be quantitatively predicted.
