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.

本文的目的是利用过渡理论研究由橡胶，铜和玻璃材料制成的矩形板的热效应。在定义变形场时，由微分方程的过渡点表示的延伸和收缩区域。分析还使中性表面将两个区域分开。已经观察到，随着材料可压缩性的增加，张力表面上的中性轴值必须集中在表面压缩上。与由铜和玻璃材料制成的矩形板相比，在由橡胶材料制成的矩形板的中性表面处的周向应力值最大。\（\ left（{\ Theta_ {1} = 0 ^ \ circ F，\ Theta_ {2} = 1000 ^ \ circ F} \ right）\）并降低温度\（\ left（{\ Theta_ {1} = 700 ^ \ circ F，\ Theta_ {2} = 0 ^ \ circ F} \ right）\）。橡胶材料制成的矩形板比铜和玻璃材料制成的矩形板更舒适。数值结果以图形方式显示。
