Nonlinear Dynamical Systems in Engineering

This book presents and extends methods for solving different types of strong nonlinearities encountered in engineering systems. Each chapter introduces a distinct approximate method, accompanied by representative examples from various fields of engineering.

This book presents and extend different known methods to solve different types of strong nonlinearities encountered by engineering systems. A better knowledge of the classical methods presented in the first part lead to a better choice of the so-called base functions. These are absolutely necessary to obtain the auxiliary functions involved in the optimal approaches which are presented in the second part.
Every chapter introduces a distinct approximate method applicable to nonlinear dynamical systems. Each approximate analytical approach is accompanied by representative examples related to nonlinear dynamical systems from to various fields of engineering.

Provides a better understanding of the base functions and the auxialiary functions for optimal approaches Inspires to appreciate the beauty as well as the usefulness of the optimal analytical techniques Includes many representative examples from to various fields of engineering Includes supplementary material: sn.pub/extras
