The propagation of Rayleigh waves along an obliquely cut surface in a directional fiber-reinforced composite

A Rayleigh type-wave, the so called ‘in-plane mode edge wave’, has been analyzed as a characteristic problem. The stress-free edge guiding the edge wave is an obliquely cut cross-section of a fiber-reinforced composite plate. The cross-section is, therefore, a non-symmetric surface of anisotropy of the composite material. Numerical results reveal characteristic features of the edge-wave propagation. They are phase velocities of the wave, particle motion by the wave, and deviation of the propagation direction of body wave components organizing the edge wave. Their characteristic features are illustrated graphically.
