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...
