Cylindrical shells with a constrained damping layer treatment are studied using three theories. The finite element method is made use of in the study. The nondimensional frequencies and loss factors predicted by the three theories are compared and the theories are evaluated. The importance of inclusion of the extensional effects in the core and its effect on the loss factor is brought out in this study.
