摘　　要：在应变具有可加性条件下,本文分析表明Eshelby线性微力学理论,包括其等效包含体方法和相应的平均化方法可推广应用于研究高刚度微粒填充高聚物的非线性粘弹性本构关系。In this paper, a micromechanical theory is used to study the nonlinear vis-coelastic constitutive relation of high rigidity particulate-filled polymers. It is demonstrated that the linear Eshelby's equivalent inclusion method and the relevant macroscopic average method can be generalized to research the constitutive relation of the composites, when the deformation of the materials is describled with linear strain and the particle's rigidity is very much higher than the matrix's.
