Wave Propagation In Structures

This book introduces spectral analysis as a means of investigating wave propagation and transient vibrations 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 powerful matrix method for analyzing complex structures as a collection of connected 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 textbook for graduate students of mechanical, civil, or aerospace engineering, the book will also be of interest to practicing engineers in these and related disciplines.
