Pre-stressed Glass
摘要
Pre-stressed glass is commonly used in architectural applications because controlled changes in the residual stress state produce useful characteristics such as higher strengths and safer fracture patterns compared to annealed glass. Common glass pre-stressing techniques are either thermal pre-stressing or chemical pre-stressing. These two processes and their effects on the performance of the glass are discussed in Sect. 6.2 and Sect. 6.3, respectively. Measuring the amount of residual stresses using photoelasticity is discussed in Sect. 6.4.
