Stress distribution in particulate filled composites and its effect on micromechanical deformation

摘要: A model was developed which assumes the spontaneous formation of an interphase around inclusions in particulate filled composites. Elastic properties change continuously from surface particle to a matrix value far it. Using first-order perturbation calculations approximate analytical solution given for distribution displacements and stresses inclusions. Fitting experimental data has shown that appropriate choice function parameters describing property changes makes possible reliable prediction composite properties. simple averaging procedure, composition dependence tensile yield stress described; accordance with observations could predict exceeding explain effect interfacial interactions. Comparison theoretical previously semiempirical one indicates main factor determining is relative load bearing capacity second component. Interacting fields compensate each other, decreasing local maxima; thus justifying procedure applied. Contradictions models are analysed areas further research also indicated paper.
