本文研究了有机玻璃梁在不同温度条件下，由两侧快速冷却产生的残余应力和变形。利用基于线性粘弹理论的基本方程，计算了该梁的残余应力和变形的理论值。另一方面，然后在相同的温度条件下对试样进行快速冷却。在快速冷却后，测量残余应力和变形。实验和理论结果进行了比较和讨论。
This paper is concerned with the residual stress and deformation of PMMA beam produced by rapid cooling from both sides under various temperature conditions. The theoretical value of the residual stress and deformation of this beam are calculated by using the fundamental equations based on the linear viscoelastic theory. On the other hand, the specimens were then actually subjected to rapid cooling under the same temperature conditions. After rapid cooling, the residual stress and deformation are measured. The experimental and theoretical results are then compared and discussed.
