| 摘 要： | 本文根据泰勒公式推导出了屈服而外凸的一般条件。在而内同性的情况下,研究了文献[1]中所推荐的新屈服准则的外凸性,讨论了屈服轨迹随 m 值的变化规仲以及屈服轨迹的变化对板枓压延性分析的影响。

| Abstract: | In this paper,a general convex condition of yield surface is proposed by the use of B.Taylor'sformula.The author also reviewed the papor[1]which pried the convex regions of a new yield cri-terion for planar isotropy,Furthermore,a discussion is given about the influences of m values on yieldsurfaces and on the analyses of sheet metal drawability. |
