The propagation of waves along an elastic layer has long been an area of active research since the later part of the 19th Century. Many contributions have already been made to the study of small amplitude wave propagation in a linear isotropic elastic layer and multi-layered structures, with traction-free boundary conditions on the upper and lower surface. However, the presence of pre-stress within an elastic body greatly increases the complexity of the problem, especially within multi-layer structures. The dispersion relations associated with a symmetric 4-ply (3 layer) laminate discussed in this thesis are derived and first solved numerically. The behaviour observed from the numerical investigation is then used to obtain asymptotic expansions for the phase speed.
