THE CONSTITUTIVE EQUATION RESEMBLANCE OF ELASTIC-PLASTIC MULTIPHASE SOLID

Based on composite materials,the equivalent elastic-plastic constitutive equations ofmultiphase solid are researched.According to the suggested definition of.constitutiveequivalence it is demonstrated that the multiphase solid,composed of several kinds ofhomogeneous elastic-plastic media that conform to the generalized normality rule,has thesame type of constitutive equations as its constituents have that also conform to thegeneralized normality rule.     

多相固体弹塑性本构方程的同类性

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.
