Abstract
An analysis of vibration of visco-elastic circular plate of variable thickness subjected to thermal gradient is presented here. The governing differential equation has been solved for free vibrations of visco-elastic circular plate, which is clamped along the boundary. Galerkin's technique has been applied to obtain corresponding natural frequencies in the form of explicit formulae. Deflection, time period and logarithmic decrement at different points for the first two modes of vibration are calculated for various types of thermal gradient and taper constant and are illustrated with tables and graphs.
