Riassunto

This book introduces spectral analysis as a means of investigating wave propagation and transient oscillations in structures. 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 new edition makes use of recent developments in hardware and software, such as FFT algorithms, and includes new chapters on structural acoustics and on connected large plates.
