The constitutive equation resemblance of elastic — Plastic multiphase solid

  • Zhang Pei-yuan
  • Tang Yu


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.

Key words

multiphase solid equivalent homogeneous medium constitutive resemblance general normality rule eqivalent elastoplastic constitutive equation
