| Abstract: | The effects of chemical strengthening on the glass＇s toughness are analyzed and discussed, based on the fracture mechanics of brittle materials and the distribution of stress in chemical strengthened glass. Then, based on the combination of Weibull distribution model and crack propagation theories, the method of proof test and prediction of lifetime for the chemical strengthened optical window glass are established. The results can be used for the strength design and testing of chemical strengthened optical window glass. |
