Two dimensional thermal effects on frequency of free vibrations of a visco-elastic square plate is considered. In this paper, the thickness varies parabolic in X- direction and thermal effect is vary linearly in one direction and parabolic in another direction. Rayleigh Ritz method is used to evaluate the fundamental frequencies. Both the modes Less
