Vibration of Periodic Structures introduces the fundamentals of the periodic structure theory. The book shows how knowledge of stop and pass bands can be utilized to develop a method for finding natural frequency distribution in a finite periodic structure. Basic concepts are then extended to wave propagation in infinitely long periodically supported beams and plates and the distribution of natural frequencies of a similar structure of finite length. The method is then extended to vibration of skin-stringer structures and the structural-acoustic properties of a section of an aircraft fuselage.This book is ideal for practicing engineers in various industries involved in the analysis of vibration of structures with periodic properties and prediction of supersonic flutter characteristics of said structures.
- Shows how the periodic structure theory can be combined with the finite element method to model a section of an airplane fuselage to study its structural-acoustic characteristics
- Features developing methods for predicting the dynamics of periodic structures in a cost-effective manner
- Guides the reader in predicting and reducing response of periodically stiffened structures to random excitations

Gautam SenGupta
Dr. Gautam SenGupta received his Ph. D. at the University of Southampton, where he developed a unique method for predicting the natural frequencies of periodic structures. After joining Boeing, he put his knowledge into practice by modelling a section of a fuselage as a periodic structure for prediction of Interior Noise. He combined the periodic structure theory with the finite element method for predicting the structural acoustic characteristics of a fuselage in a cost-effective manner. He retired as a Technical Fellow of the Boeing Company in Seattle, where he was also involved in developing methods for predicting Airframe noise, and transonic flutter characteristics of airplanes. Before joining Boeing, he worked at NASA-Langley as a Research Associate. He served as a Specialist Engineer in Acoustic Fatigue at the Engineering Sciences Data Unit of the Royal Aeronautical Society of England. He received his B. Tech from IIT, Kharagpur, and B. Sc from Presidency College, Calcutta.
