本文研究了带有微小压痕裂纹的钠钙玻璃试件在惰性环境中的双轴向弯曲强度分布和加载应力速率对试件疲劳强度的影响。试件在蒸馏水中的断裂强度、断裂概率及加载应力速率三者之间的关系可以用一个两参数的Weibull函数进行描述。本文还将钠钙玻璃试件的双轴向弯曲强度和与其相应的单轴向弯曲(四点弯曲)强度进行了比较。
In this paper, the biaxial flexural strength distribution and the effect of loading stress rate on the fatigue strength of the test specimens of the soda-lime glass specimens with micro-indentation cracks are studied. The relationship between the fracture strength, fracture probability and loading stress rate of the specimen in distilled water can be described by a two-parameter Weibull function. This paper also compares the biaxial bending strength of soda-lime glass specimens with their corresponding uniaxial bending (four-point bending) strength.
