Preface This book follows the same concept of the first two volumes and is based on the ASME 2013 and 2012 Congress in the track of Dynamics Systems and Control, OptimalApproachesinNonlinearDynamics,whichwereorganizedbytheeditors. The nonlinear approaches and techniques have been developed since decades ago.

Linearization ends up with simplification, and it damages the original characteristics of the systems. Such simplifications usually lead to inaccuracy, misunderstanding, or even incorrect conclusions. For example, Hooke’s law including the generalized Hooke’s law is linear and it composes the foundation of linear elasticity and dominates numerous solutions of physical systems and mechanical designs. However, no material is perfectly linear.Anymaterialusedintherealworldcanactuallybeanonlinearandcomplex system, not only due to its material or structure nonlinearity but also due to the inhomogeneousnessandanisotropyofthematerials.

Throughout the book, great emphases are placed on engineering applications, Preface ix physical meaning of the nonlinear systems, and methodologies of the approaches in analyzing and solving for the systems. Topics that have been selected are of high interest in engineering and physics. An attempt has been made to expose the engineersandresearcherstoabroadrangeofpracticaltopicsandapproaches.The topics contained in the present book are of specific interest to engineers who are seekingexpertiseinnonlinearanalysis,mathematicalmodelingofcomplexsystems, optimization of nonlinear systems, non-classical engineering problems, and future ofengineering. The primary audience of this book is the researchers, graduate students and engineers in mechanical engineering, engineering mechanics, electrical engineer- ing,civilengineering,aerospaceengineering,oceanengineering,mathematics,and science disciplines. In particular, the book can be used as a book for the graduate students as well as senior undergraduate students to enhance their knowledge by taking a graduate or advanced undergraduate course in the areas of nonlinear science, dynamics and vibration of discrete and continuous system, structure dynamics,andengineeringapplicationsofnonlinearscience.Itcanalsobeutilized as a guide to the readers’ fulfilment in practices. The covered topics are also of interesttoengineerswhoareseekingtoexpandtheirexpertiseintheseareas. Organizationofthe Book The main structure of the book consists of two parts of analytical and practical nonlinearity, including 12 chapters. Each of the chapters covers an independent topicalongthelineofnonlinearapproachandengineeringapplicationsofnonlinear science. The main concepts in nonlinear science and engineering applications are explained fully with necessary derivatives in detail.
