Vibrations of Thick Cylindrical Structures

There has been increased research and development activity in the field of vibration and passive vibration control of long and thick cylindrical structures. This book includes a conceptual framework to the subject, including modal analysis.

Due to strong potential applications and more demanding requirements imposed upon long and thick cylindrical structures, there has been increasing research and development activities during recent years in the field of vibration and passive vibration control of these types of structures. An important step in the study of cylindrical structures is the determination of their vibration modal characteristics. This modal information plays a key role in the design and vibration suppression of these structures when subjected to dynamic excitations. Most reported studies on the dynamic response of cylindrical structures have been restricted to the application of the shell theories. These theories are based on a number of simplifying assumptions. The most important of which is, the considered shell must be relatively thin to assume constant stresses within the cylinder. Therefore, due to this limitation, shell theories are inadequate to accurately describe all possible vibration modes in thick cylindrical structures. The primary scope of this book is to address these problems by applying the theory of elasto-dynamics.

Provides a conceptual framework that includes exposure to the required background in mathematics, fundamentals of theory of elasticity, modal analysis, and constrained-layer damping treatment Provides a systematic solution for modal analysis of thick cylinders and panels and is to extend the solution to vibration of layered cylindrical structures The provided solution for the continuous elastic medium is extended to visco-elastic medium by considering complex elastic moduli for the medium Provides a systematic solution for each cylindrical layer included in the constrained layer-damping treatment of thick cylindrical structures by satisfying the compatibility of stresses and displacement at all interfaces Includes supplementary material: sn.pub/extras
