Abstract

In this work the effective moduli of a composite material have been found by employing the finite-element method. The correspondence between the actual composite and its equivalent homogeneous anisotropic material is established on the requirement of equality of the total strain energies for the two media. The method is applied to the unidirectional fiber composites, the short unidirectional fiber composite, and the lamellar composite, and the results compare satisfactorily with available analytical data.
