TECHNOLOGY Analysis of Natural Vibration of Visco-Elastic Rectangulr Plate with Thickness and Temperature Variation

Visco- Elastic Plates are being increasingly used in the aeronautical and aerospace industry as well as in other fields of modern technology. Plates with variable thickness are of great importance in a wide variety of engineering applications i.e. nuclear reactor, aeronautical field, naval structure, submarine, earth-quake resistors etc. A mathematical model is presented for the use of engineers and research workers in space technology, have to operate under elevated temperatures.It is assumed that temperature varies exponentially in x-direction: 0 1 1 1 x ae e e
