TLDR
In this paper, the importance of extensional effects in the core and its effect on the loss factor is brought out in the study of cylindrical shells with a constrained damping layer treatment.Abstract:
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 studyread more

Linear and nonlinear vibration analysis of sandwich cylindrical shell with constrained viscoelastic core layer
TL;DR: In this article, the effect of geometric nonlinearity due to the large deformation of the shell has also been considered assuming small strain and moderate rotation, and it is shown that slippage between layers at the interfaces leads to reduction in loss factor at the majority of modes.
