Wave Propagations in Orthogonally Reinforced Fiber Composites. (A Discrete Model for Reinforced Composites Viewed as Polar Media).
Abstract
A discrete model for a composite reinforced with two sets of orthogonally interlocking fibers is given, and the propagation of plane harmonic waves in such a medium is investigated. The composite considered consists of two sets of orthogonal equivalent elastic fibers and a matrix material whose elastic properties are different from those of the fibers. Assuming a considerably large flexural rigidity for the fibers and strong bonds at the joints, the difference equations governing the translational and rotational motions of the joints are obtained. The dispersion relations of waves propagating in the medium are studied and various special cases are discussed.
