Nonlinear dynamical systems in engineering: some approximate approaches

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 obtainthe 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 approachis 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 INDICE: Introduction. Perturbation method (Lindstedt-Poincaré). The methodof harmonic balance. The method of Krylov and Bogolyubov. The method of multiple scales. The optimal homotopy asymptotic method. The optimal homotopy perturbation method. The optimal variational iteration method. Optimal parametric iteration method.
