3D Micromechanical Modeling of Particulate Composite Materials with Imperfect Interface
摘要
In this article, we study the effective elastic and plastic properties of particle-reinforced composite materials with imperfect interface. The imperfect interface is described by a spring-type model assuming that the traction continuity remains intact, while the displacement experiences a jump proportional to the interfacial traction. Both the tangential and normal displacement discontinuities at the interfaces are considered and the effective elastic moduli are obtained using a generalized version of dilute model, self-consistent model, MoriTanaka model, and differential model. A comparison between the effective elastic moduli obtained by these different models is made, and the determination of an effective plastic behavior of particulate composite materials, by means of the MoriTanaka model and secant moduli method, is also discussed. Finally, we examine the influence of interfacial compliance on the macroscopic averaged mechanical properties of composite materials.
