This 2007 book concerns the vibration and the stability of slender structural components. The loss of stability of structures is an important aspect of structural mechanics and is presented here in terms of dynamic behavior. A variety of structural components are analyzed with a view to predicting their response to various (primarily axial) loading conditions. A number of different techniques are presented, with experimental verification from the laboratory. Practical applications are widespread, ranging from cables to space structures. The book presents methods by which the combined effects of vibration and buckling on various structures can be assessed. Vibrations and buckling are usually treated separately, but in this book their influence on each other is examined together, with examples when a combined approach is necessary. The avoidance of instability is the primary goal of this material.

Transport engineering structures are subjected to loads that vary in both time and space. In general mechanics parlance such loads are called moving loads. It is the aim of the book to analyze the effects of this type of load on various elements, components, structures and media of engineering me chanics. In recent years all branches of transport have experienced great advances characterized by increasingly higher speeds and weights of vehicles. As a result, structures and media over or in which the vehicles move have been subjected to vibrations and dynamic stresses far larger than ever before. The author has studied vibrations of elastic and inelastic bodies and structures under the action of moving loads for many years. In the course of his career he has published a number of papers dealing with various aspects of the problem. On the strength of his studies he has arrived at the conclusion that the topic has so grown in scope and importance as to merit a comprehensive treatment. The book is the outcome of his attempt to do so in a single monograph.

Covering the whole spectrum of vibration theory and its applications in both civil and mechanical engineering, Mechanical and Structural Vibrations provides the most comprehensive treatment of the subject currently available. Based on the author s many years of experience in both academe and industry, it is designed to function equally well as both a day–to–day working resource for practicing engineers and a superior upper–level undergraduate or graduate–level text. Features a quick–reference format that, Mechanical and Structural Vibrations gives engineers instant access to the specific theory or application they need. Saves valuable time ordinarily spent wading through unrelated or extraneous material. And, while they are thoroughly integrated throughout the text, applications to both civil and mechanical engineering are organized into sections that permit the reader to reference only the material germane to his or her field. Students and teachers will appreciate the book′s practical, real–world approach to the subject, its emphasis on simplicity and accuracy of analytical techniques, and its straightforward, step–by–step delineation of all numerical methods used in calculating the dynamics and vibrations problems, as well as the numerous examples with which the author illustrates those methods. They will also appreciate the many chapter–end practice problems (solutions appear in appendices) designed to help them rapidly develop mastery of all concepts and methods covered. Readers will find many versatile new concepts and analytical techniques not covered in other texts, including nonlinear analysis, inelastic response of structural and mechanical components of uniform and variable stiffness, the "dynamic hinge," "dynamically equivalent systems," and other breakthrough tools and techniques developed by the author and his collaborators. Mechanical and Structural Vibrations is both an excellent text for courses in structural dynamics, dynamic systems, and engineering vibration and a valuable tool of the trade for practicing engineers working in a broad range of industries, from electronic packaging to aerospace. Timely, comprehensive, practical––a superior student text and an indispensable working resource for busy engineers Mechanical and Structural Vibrations is the first text to cover the entire spectrum of vibration theory and its applications in both civil and mechanical engineering. Written by an author with over a quarter century of experience as a teacher and practicing engineer, it is designed to function equally well as a working professional resource and an upper–level undergraduate or graduate–level text for courses in structural dynamics, dynamic systems, and engineering vibrations. Mechanical and Structural Vibrations: ∗ Takes a practical, application–oriented approach to the subject ∗ Features a quick–reference format that gives busy professionals instant access to the information needed for the task at hand ∗ Walks readers, step–by–step, through the numerical methods used in calculating the dynamics and vibration problems ∗ Introduces many cutting–edge concepts and analytical tools not covered in other texts ∗ Is packed with real–world examples covering everything from the stresses and strains on buildings during an earthquake to those affecting a space craft during lift–off ∗ Contains chapter–end problems––and solutions––that help students rapidly develop mastery of all important concepts and methods covered ∗ Is extremely well–illustrated and includes more than 300 diagrams, tables, charts, illustrations, and more

A presentation of the theory behind the Rayleigh-Ritz (R-R) method, as well as a discussion of the choice of admissible functions and the use of penalty methods, including recent developments such as using negative inertia and bi-penalty terms. While presenting the mathematical basis of the R-R method, the authors also give simple explanations and analogies to make it easier to understand. Examples include calculation of natural frequencies and critical loads of structures and structural components, such as beams, plates, shells and solids. MATLAB codes for some common problems are also supplied.
