Abstract:

In the current analysis vibration characteristics of a cylindrical shell composed of three layers are examined. This configuration is framed by three layers of different materials in thickness direction such that the inner and outer layers are of isotropic nature and functionally graded material is used for the middle layer. The shell is supported on Winkler and Pasternak foundations. Love shell equations are considered to study the vibration problem. The Winkler and Pasternak foundations are combined with the shell dynamical equations in the transverse direction. The present shell problem is solved by using wave propagation approach. A few comparisons of shell frequencies are done to verify the validity and accuracy of the present technique.
