In this section, first, wave propagation in elementary laminated composite beams is discussed. The main objective is to bring out the effect of stiffness and inertial coupling on the overall wave response behavior. Next, the same is discussed for higher order composite beams. Here, the effect of lateral contraction is also introduced. The method of treating various damping schemes is addressed. The last part of this chapter deals with the spectral element formulation of layered composite tube. A number of numerical examples are provided to highlight the wave behavior. For many examples, comparisons of spectral solutions with regular FEM are provided.
