本文首先分析了在双向平面应力作用下双曲弹塑性壳单元的屈曲起始。塑性屈服描述使用最近提出的各向异性金属板材的标准。并将所得的屈服极限曲线与以往不同屈服准则下的结果进行了比较。还使用Abaqus/Explicit代码进行了深冲实验的有限元（FE）模拟，目的是将与分析模型的预测和文献中的实验有关的开始变形的FE结果进行比较。
An analysis of the onset of wrinkling is first developed for a doubly curved, elastic–plastic shell element submitted to a biaxial plane stress loading. Plastic yielding is described using a criterion recently proposed for anisotropic sheet metals. The wrinkling limit curves obtained with this analysis are compared with previous results based on different yield criteria. Finite element (FE) simulations of a deep-drawing experiment are also performed using the Abaqus/Explicit code with the aim of comparing the FE results relating to the initiation of wrinkling with the predictions of the analytical model and with experiments from the literature.
