摘要
用预加载技术测试了钠钙玻璃试件的动疲劳强度,并分析了预加载时动疲劳强度及其分布的影响.结果表明,如果预加载载荷小于试件动疲劳强度的80%,测得的动疲劳强度与试件真实动疲劳强度的差异可以忽略.
The dynamic fatigue strength of soda-lime glass is experimentally determined by the preloading technique. The effect of the preloading on the dynamic fatigue strength and its distribution is analyzed. The results indicate that discrepancy between the dynamic fatigue strength determined by preloading technique, σ_f' and the true dynamic fatigue strength of specimens σ_f can be neglected if the preloading stress is less than 0. 8σ_f.
