In the course of time, the study of vibration of plates with thickness variability has acquired great importance in nuclear reactor technology, earth-quake resistant structures, aeronautical field, naval structures and machine designs etc. Plates of variable thickness are mainly used for two fold requirements of safety and economy. Therefore, it becomes the need of the hour to provide some authentic theoretical mathematical models for the help of mechanical/design engineers & scientists so that before finalizing any design or mechanical structure, they can use of them with practical approach...

In the modern epoch of science and technology; scientists, engineers & practitioners have become more interested to analyze the vibrational characteristics of structural components which are mainly operated under elevated temperature i.e. space technology, nuclear energy applications, high speed atmospheric flights etc. Due to the influence of temperature, the physical properties of materials change significantly. Further, the use of various plate type structural elements under high temperature environments, particularly in space vehicles and modern missiles, demand that non-homogeneity of...
