摘要: In the current analysis vibration characteristics of a cylindrical shell composed three layers are examined. Vibration shells is accomplished for their involvement in various areas engineering and technology. Shell behavior depends upon on different geometrical material parameters parameters. They provide maximum stability physical system. There graduation distribution constituent materials functionally graded controlled by polynomial, exponential trigonometric volume exponent fraction laws. present study whereas middle layer consists extreme isotropic nature. Material composition FG governed Impact these laws examined frequencies Love’s thin theory adopted motion equations. The with FGM will be expressed using Raleigh-Ritz technique this method. Three used to define tri-layer shells. Rayleigh-Ritz applied form frequency equation which solved MATLAB software. validity accuracy method investigated number comparisons numerical results.
