An introduction to the fundamentals and applications of dynamics, with a particular emphasis on vibrations for students and practitioners of engineering. It covers the basic laws of kinematics and kinetics, the principles of d'Alembert, Jourdain, and Hamilton, as well as the Lagrangian and Newton-Euler equations of motion, linear discrete and continuous vibration systems, solution methods, and approximation methods by Ritz and Galerkin, time behavior, stability, nonlinear mechanics, solution methods using the example of a single-degree-of-freedom oscillator, stability, and phenomena of vibration generation; externally excited, parameter-excited, and self-excited vibrations. The third edition of this well-established work has been thoroughly revised, didactically improved, updated, and adapted to international standards.
