Analytical solution of a vibrational problem for visco-elastic plate with Kelvin type boundary conditions

Within this time of science and technology, tapered plates with different geometry conditions are used as a for the construction of wings and blades of aeronautical as well as engineering structures. The main aim of current work is to analyze the vibration of rectangular structure tapered plate with thermal effect variation along x and y axis. Rayleigh-Ritz method is use for judgment the solution of frequency equation. Now for several values of thermal gradient, aspect ratio and taper constant are considered to calculate structural parameters such as logarithmic decrement, time period and deflection.
