Abstract: | With respect to obtaining the effective elastic moduli of the composite, the present theory differs from both Eshelby's equivalent
inclusion method and Hill's self-consistent one, both of which only consider the mechanical properties of the matrix and inclusions
(fibers). In fact, the inclusion-inclusion interaction is more pronounced when the volume fraction of inclusions of the composite
increases. Hence, in this paper the effective elastic moduli of the composite are derived by taking into account the shapes,
sizes and distribution of inclusions, and the interactions between inclusions. In addition, it is more convincing to assume
short-fibers as cylindrical inclusions as in the present paper than as ellipsoidal ones as in others7,8]. Finally, numerical results are given. |
