威布尔累积分布函数通常用于描述在测量陶瓷强度时观察到的宽分散性。随着微观力学模型[1-4]的发展，它也被用来描述钢在低温下在转变范围的下部的韧性，当断裂发生在解理时。对于特定的材料特性和试样厚度，韧性水平K下的累积失效概率~由下式给出：
The Weibull cumulative distribution function is commonly used to describe the wide scatter observed in measuring the strength of ceramics. With the development of micro-mechanical models [1-4] it has also been used to describe the toughness of steels at low temperature in the lower part of the transition range, when failure occurs by cleavage. For specific material properties and specimen thickness, the cumulative failure probability~ at a toughness level K is given by
