This volume provides an up-to-date overview of statistical energy analysis and its applications in structural vibration. It brings together nine articles by experts in S.E.A. from around the world, beginning with an introduction and overview of the technique describing its key successes, potential and limitations. Following chapters look in more detail at a selection of cases and examples that together illustrate the scope and power of the technique. The editors have included a chapter by Chohan et al. discussing nonconservatively coupled systems.
