| Abstract: | Correlating the effective properties of composite materials with their microstructures is a basis for optimization design of composite materials. In this review article, the focus is on the basic ideas and major methods for analyzing the effective properties, mostly within the frame-work of elasticity. After a brief discussion on the concept of representative volume element, the micromechanics methods, major results and recent advances on the effective properties of compos- ite materials are described in a fairly comprehensive manner on three predominate aspects: the universal relations, the upper and lower bounds and the approximate estimates. The relations and differences among various models, methods and estimates are analyzed based upon the configu-ration concept and microstructures. Finally, some comments are made on some research topics of current interest and some open questions in the field of effective properties of heterogeneous materials. |
