Vibration of Periodic Structures (eBook, ePUB)

• Format: ePub

Produktbeschreibung

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

Autorenporträt

Dr. Gautam SenGupta received his BSc (Physics) from Presidency College, Calcutta, India, his BTech (Mechanical Engineering) from IIT, Kharagpur, India, and his PhD from the University of Southampton, United Kingdom, where he developed a unique method for predicting the natural frequencies of periodic structures. He worked as a Specialist Engineer in Acoustic Fatigue at the Royal Aeronautical Society of England, and at NASA-Langley as a Research Associate. He joined Boeing in 1973, where he applied the Periodic Structure Theory to predict and control the structural acoustic characteristics of an airplane fuselage in a cost-effective manner. He retired in 2016 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. In addition, he has served as an Affiliate Professor at the University of Washington, where he taught courses on Structural Dynamics and related subjects.
