Computation of vibrational frequency on trapezoidal plate with non homogeneity effect

The central key of the present paper is to compute vibrational frequency using non-homogeneous trapezoidal plate under 2D temperature. It is assumed that the plate's thicknesses vary parabolic in one direction and linear in other direction. The density of the plate is taken linear in one dimension as the plate is non-homogeneous. Two term deflection function with boundary condition (C-S-C-S) is taken into account. Rayleigh-Ritz technique is used for finding vibrational frequency. The effects of other parameters on vibration have also been studied. Results are calculated using software MAPLE and presented in tabular form.
