Structural Acoustics and Vibration presents the modeling of vibrations of complex structures coupled with acoustic fluids in the low and medium frequency ranges. It is devoted to mechanical models, variationalformulations and discretization for calculating linear vibrations in the frequency domain of complex structures. The book includes theoretical formulations which are directly applicable to develop computer codes for the numerical simulation of complex systems, and gives a general scientific strategy to solve various complex structural acoustics problems in different areas such as spacecraft, aircraft, automobiles, and naval structures. The researcher may directly apply the material of the book to practical problems such as acoustic pollution, the comfort of passengers, and acoustic loads induced by propellers. Structural Acoustics and Vibration considers the mechanical and numerical aspects of the problem, and gives original solutions to the predictability of vibrations of complex structures interacting with internal and external, liquid and gaseous fluids. It is a self-contained general synthesis with a didactic presentation and fills the gap between analytical methods applied to simple geometries and statistical methods, which are useful in high frequency structural acoustic problems.

From the Back Cover:

This book deals with the mechanical modeling and solving methods for calculating linear vibrations of complex structure when couple with acoustic fluids, in both the low-and the medium-frequency ranges. Complex structures are considered, allowing the researcher to apply the material directly to practical vibration problems; these include acoustic pollution and acoustic loads in different areas, such as spacecraft, aircraft, automobiles, and naval structures.

Advanced mechanical and numerical models are used throughout, and original solutions to the prediction of linear vibrations of complex structures interacting with internal and external fluids, both liquid and gaseous, are given. The formulations presented are directly applicable for developing computer codes for the numerical simulation of complex structural-acoustics systems.

Structural Acoustics and Vibration will prove invaluable to both postgraduate and postdoctoral students in Applied, Computational and Structural Mechanics. The book is also essential reading for researchers in Structural Dynamics and Acoustics, and professionals working within the aerospace and automobile industry, as well as in the fields of Naval and Civil Engineering.
