Short description
Providing a first course on vibrations of continuous system, Vibrations and Waves in Continuous Mechanical Systems deals with the underlying theory and analysis techniques for continuous system models of a wide class of mechanical systems. The prerequisites for the book are the basic undergraduate courses on Mathematics, Mechanics/Physics, Theory of Elasticity, and Vibrations of Discrete Systems. The self-contained book offers a number of new topics and exercises that form essential stepping-stones to the present level of research in the area of vibrations in continuous systems.
