Advanced Structural Dynamics

Advanced Structural Dynamics Edited by J. DONÉA APPLIED SCIENCE PUBLISHERS This book presents a review of modern numerical procedures for struc­tural dynamics which are illustrated by their application to significant practical problems. The first part of the text covers techniques for dynamic response in the frequency domain as well as methods for transient response by time integration. The variational methods of structural dynamics are presented and their finite element implementation discussed in detail. The use of modal methods for calculating a transient response is described with a particular emphasis on the problem of reducing a multi-degree of freedom system to a smaller set of degrees of freedom. A review is then made of implicit, explicit and combined explicit-implicit opera­tors for transient response by time integration. This is followed by a presentation of finite element formula­tions adapted to implicit and explicit time integrators. The second part of the text is devoted to a detailed presentation of practical applications. These cover a wide range of situations including dynamic fracture mechanics, anti-missile design, pipe whip accidents and transient fluid-structure interaction. The latter topic is given particular attention in view of its growing importance in nuclear reactor safety studies. Applications are de­scribed based on finite difference, finite element and boundary integral methods.
