Ebook: Wave Propagation in Structures: Spectral Analysis Using Fast Discrete Fourier Transforms

Mechanical engineering. an engineering discipline borne of the needs of the in­ dustrial revolution. is once again asked to do its substantial share in the call for industrial renewal. The general call is urgent as we face profound issues of produc­ tivity and competitiveness that require engineering solutions. among others. The Mechanical Engineering Series features graduate texts and research monographs intended to address the need for information in contemporary areas of mechanical engineering. The series is conceived as a comprehensive one that covers a broad range of concentrations important to mechanical engineering graduate education and re­ search. We are fortunate to have a distinguished roster of consulting editors on the advisory board. each an expert in one the areas of concentration. The names of the consulting editors are listed on the facing page of this volume. The areas of concentration are: applied mechanics; biomechanics; computational mechan­ ics; dynamic systems and control; energetics; mechanics of materials; processing; thermal science; and tribology.

This book introduces spectral analysis as a means of investigating wave propagation and transient oscillations in structures. After developing the foundations of spectral analysis and the FFT (fast Fourier transform) algorithm, the book provides a thorough treatment of waves in rods, beams, and plates and introduces a novel matrix method for analyzing complex structures as a collection of waveguides. The presentation includes an introduction to higher-order structural theories, the results of many experimental studies, and practical applications. Pertinent problems after each chapter and an extensive bibliography form the basis for further study. Intended as a texbook for graduate students of mechanical or aerospace engineering, the book will also be of interest to practicing engineers in these and related disciplines. This second edition has been revised throughout, incorporating recent developments in hardware and software, such as FFT algorithms, as well as new chapters on structural acoustics and on connected large plates.
