Abstract : The Bedford-Stern theory of composites is used to predict the phase velocity of plane stress waves in a fiber-reinforced elastic solid. The phase velocity is found as a function of the wave number and as a function of the direction of propagation of the wave relative to the fiber direction. The particle motion of each of the constituents is solved for at various wave numbers. It is found that there are four possible propagation velocities in a binary mixture of this type, and that two of these waves correspond to nearly shear motion while the remaining two correspond to nearly compressional motion. Several interesting and unexpected phenomena were found to occur at certain frequencies. (Author-PL)
