The Role of Effective Moduli in the Elastic Analysis of Composite Laminates

  • N. J. Pagano
Part of the Solid Mechanics and Its Applications book series (SMIA, volume 34)


The purpose of this introductory chapter is to review some of the salient features of micromechanics of composite media. In contrast to the extensive literature reviews given by Hashin (1964) and Chamis and Sendeckyj (1968) which treat the various approaches used in the determination of effective properties of heterogeneous bodies, our emphasis will be placed on the interpretation and application of effective elastic moduli. Physical and mathematical definitions of effective moduli are compared and their use in the analysis of engineering composite laminates will be discussed. Finally, we shall present an approach to treat nonuniform (linear variation) macroscopic membrane stresses within composite laminates.
