Introduction,The purpose of this small book is to introduce 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.

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.

Flexural Waves in Beams,Besides the rod, the other major structural component of importance is the beam. The purpose of this component is to support lateral loads and, consequently, the displacement is off the centerline. The dynamic behavior generated is called ..
