Beschreibungen

This landmark book deals with nonlinear normal modes (NNMs) and nonlinear mode localization. Offers an analysis which enables the study of various nonlinear phenomena having no counterpart in linear theory. On a more theoretical level, the concept of NNMs will be shown to provide an excellent framework for understanding a variety of distinctively nonlinear phenomena such as mode bifurcations and standing or traveling solitary waves.

Vibration analysis of nonlinear systems poses great challenges in both physics and engineering. This innovative book takes a completely new approach to the subject, focusing on nonlinear normal modes (NNMs) and nonlinear mode localization, and demonstrates that these concepts provide an excellent analytical tool for the study of nonlinear phenomena that cannot be analyzed by conventional techniques based on linear or quasi-linear theory.<br> <br> Written by professor Alexander F. Vakakis and four colleagues from Russia and the Ukraine, the book employs the similarity of NNMs to the normal modes of classical vibration theory to create a new perspective on this highly specialized, yet steadily growing field. Providing a solid foundation in theory, the authors explain, for example, the design of systems with passive or active motion confinement properties and examine applications of essentially nonlinear phenomena to the vibration and shock isolation of flexible, large-scale structures.<br> <br> Much of the material presented is completely new or appearing here for the first time in Western engineering literature--including numerous mathematical techniques for studying NNMs, their bifurcations, and the localization phenomena associated with them. The authors describe strongly nonlinear analytical methodologies that permit the analytical treatment of oscillators in strongly nonlinear regimes. They then demonstrate the application of these methodologies in numerous practical engineering and physics problems. Also presented is the method of nonsmooth temporal transformations, which enables analytic perturbation studies of strongly nonlinear oscillations, a new asymptotic methodology for analyzing standing solitary waves in some classes of nonlinear partial differential equations, and some new results on localized or nonlocalized oscillations of vibro-impact systems.<br> <br> Supplemented with an extensive bibliography and numerous illustrations and examples that demonstrate techniques and applications, Normal Modes and Localization in Nonlinear Systems is a useful text and professional guide for physicists studying nonlinear oscillations and waves, for vibration specialists, design engineers, and researchers studying nonlinear dynamics, and for graduate students in applied mechanics and mechanical engineering. It also offers a multitude of new concepts and techniques that can form the basis for future research in nonlinear dynamics and vibrations.<br> <br> A complete guide to the theory and applications of nonlinear normal modes and nonlinear mode localization<br> <br> This landmark volume offers a completely new angle on the study of vibrations in discrete or continuous nonlinear oscillators.
