A Two-Dimensional Lattice Model for Composites Reinforced with Orthogonal Fibers.

摘要

A two-dimensional lattice dynamics 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. The dispersion relations of waves propagating in the medium are studied and various special cases are investigated.
