| 摘 要： | 本文从 Drucker 公设出发,建立了弹塑性耦合情况下的广义正交法则,讨论了屈服面的凸凹性及弹塑性耦台情况下的加载准则。文中还对 Drucker 公设与Ilyushin 公设之间的联系及 Drucker 公设的适用范围进行了讨论。

| Abstract: | In this paper,the generalized normality rule for an elastoplastic co- upling material is set up based on the Drucker's postulate of plasticity. So do the loading criterion and the convexty or cancave of the loading su- rface in stress space.The relationship between Drucker's postulate and Ilyushin's postulate as well as the applicable range of Drucker's postul- ate is discussed. |
