FREE VIBRATION OF RHOMBIC PLATE WITH VARYING THICKNESS IN 2D AND THERMAL EFFECT IN X-DIRECTION

Rapid advancements made in materials science and manufacturing technologies has lead to the application of composite materials in various areas of engineering applications like aerospace industries, marine structures, automobiles, power plant systems etc. The object of this paper is to investigate the vibration problem of rhombic plate with 2D linearly varying thickness and Thermal effect linearly in x-direction. Rayleigh-Ritz technique is used to obtain a frequency equation with a two-term deflection function. 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.
