Effect of interface on the elastic stiffness of composites

Research output: Contribution to journalArticle


The paper investigates the effect of interface on the transverse effective elastic moduli of composites. Initially, the micromechanics approach is used by solving the elasticity problems of a single fiber (inclusion) embedded in the infinite matrix subjected to mechanical loadings. The interface is varied theoretically by considering two models. The actual stress field in the vicinity of fiber is obtained by using Mori Tanaka theory to include the effect of fiber interaction. Then, the results obtained from the micromechanics analysis are used to predict the macroscopic elastic moduli of composites with the imperfectly bonded interfaces. The influence of various mechanisms at the interface is presented and the results are compared with the perfectly bonded case.
