Effective stiffness theory of the Nth order is derived for the modeling of the three-dimensional time-dependent motion of a fiber-reinforced composite. The fibers are assumed to be of a rectangular cross section and are imbedded in the matrix in the form of a doubly periodic array. The resulting theory represents the composite as a higher order homogeneous continuum with microstructure whose motion is governed by higher order displacements. The derivation is systematic and can be applied to elastic as well as anelastic composites to the desired degree of accuracy.
