Vibration of Visco-elastic Rhombic Plate with Varying Thickness and Thermal Gradient

A theoretical model presented here is to study the effect of thermal gradient on vibration of visco-elastic rhombic plate of variable thickness. Temperature and thickness vary linearly along the x-direction. Rayleigh-Ritz technique is used to obtain a frequency equation with a two-term deflection function. Assumed that the plate is clamped on all the four edges. Numeric values of frequencies are calculated for different values of thermal gradient, taper parameter and skew angle for both the modes of vibration. The results are presented in tabular forms.
