Abstract
The objective of this paper is to present the study of thermal effect in the rectangular plate made of rubber, copper and glass materials using transition theory. The extension and contraction regions presented by the transition points of the differential equation in defining the deformed fields. The analysis also makes the neutral surface separating the two regions. It has been observed that with increased compressibility of materials, the value of neutral axis on the surface of tension must be concentrated on the surface compression. The value of circumferential stress has a maximum at the neutral surface of the rectangular plate made of rubber material in comparison with rectangular plate made of copper and glass materials. With the introduction of thermal effects the value of the circumference as well as radial stresses increases in temperature \(\left( {\Theta_{1} = 0^\circ F,\Theta_{2} = 1000^\circ F} \right)\) and decreases in temperature \(\left( {\Theta_{1} = 700^\circ F,\Theta_{2} = 0^\circ F} \right)\). Rectangular plate made of rubber material is more comfortable than that of copper and glass materials. Numerical results are shown graphically.
