摘要
本文从理论上推导出了脆性材料的累积损伤概率公式,建立起了用损伤概率理论及计算机图形技术相结合求解Weibull参数的新方法,并详细研究了Weibull参数之一的m值,揭示出它是质量控制的关键参数,同时还研究了试件体积对损伤概率的影响.
The formulas for cumulative failure probability of brittle material are derived theoretically. A new routine to find out Weibull parameters has been established with the help of computer graphic technique. Weibull parameter m is discussed in details and it is revealed that m is a key factor for quality control. The influence of specimen's volume on failure probability is also discussed.
