AB - This paper examines the propagation of waves in a 2-ply laminate composed of a transversely isotropic elastic material with the fibre direction in the two plies being at right angles to each other. Attention is confined to waves propagating in the fibre direction in one of the plies. The dispersion equation, relating the wave speed to the wavelength, is derived and is solved numerically for a number of different values of the ratio of the thickness of the two layers. The long and short wavelength behaviour is examined analytically. Comparisons are made between this asymmetric composite and a symmetric 3-ply laminate composed of the same material. Results are plotted for the fundamental mode and first harmonic of the dispersion relation of the asymmetric laminate. The high frequency limit of the dispersion curve for the fundamental mode is the velocity of a Rayleigh surface wave in the cross-fibre direction, whilst that of the first harmonic is the velocity of a shear wave in the cross-fibre direction. Corresponding results are obtained for the ideal material which is inextensible in the direction of transverse isotropy, and these are compared with those for the extensible material.
