摘　　要：本文以复合材料为背景,讨论多相固体即混合物的等效弹塑性本构方程.按照所提出的等效本构方程的定义,文章证明,由服从广义正交法则的多种均匀的弹塑性介质组成的混合物具有与它的组分介质同类的、也服从广义正交法则的等效本构方程.Based on composite materials, the equivalent elastic-plastic constitutive equations of multiphase solid are researched. According to the suggested definition of constitutive equivalence it is demonstrated that the multiphase solid, composed of several kinds of homogeneous elastic-plastic media that conform to the generalized normality rule, has the same type of constitutive equations as its constituents have that also conform to the generalized normality rule.
