Introduction,This small book is an introduction to the spectral analysis method as a means of solving wave propagation problems in structures. The emphasis is on practical methods from both the computational and applications aspects, and reference to experimental results is made whenever possible.

The Spectral Element Method,The only way to efficiently handle wave propagation problems in structures with complicated boundaries and discontinuities is to develop a matrix methodology for use on a computer. In this chapter, we develop such a method.

Longitudinal Waves in Rods,Rods and struts are very important structural elements and form the basis of many truss and grid frameworks. Since their load bearing capability is axial, then as waveguides they conduct only longitudinal wave motion.

Spectral Analysis of Wave Motion,ion or . of components. Working in terms of the spectrum is called . In wave analysis, the time domain for a motion or response is from minus infinity to plus infinity. Functions in this domain are represented by a continuous distribution of components which is known as its continuous Fourier transf

Higher-Order Waveguides,these models. We will try to clarify the issues involved by considering some exact solutions of waves in waveguides; this is a difficult and mathematically cumbersome area so only a limited number of aspects will be treated. The chapter begins by looking at waves in extended media and waves in bound
