1)  crack rate
开裂率
1.
The flattening tests of metallic pipes with or without plate core indicated that (1) when the top and bottom sections of metallic pipes were flattened the results of the two types of tests were the same, (2) in further flattening, the top and bottom sections of hollow metallic pipes were dented and the crack rate was higher than those pipes tested with plate core at the same flattened distance.
通过对金属管内加板芯和不加板芯两种压扁方式的对比试验,结果表明:(1)当金属管由正常圆压至上下壁成平面时,两种压扁方式的试验结果相同;(2)在继续压扁时,无板芯金属管的上下壁由平面状态向管内凹入,其开裂率高于同样压扁距离下的有板芯金属管。
2)  crack probability
开裂概率
1.
A concept of dry shrinkage crack probability (C) has been put forward by which the concrete dry shrinkage crack probability could be devided into three levels named as: C≥60%(high risk),40%≤C<60%(medium risk)and C<40%(low risk).
介绍了一种评价混凝土收缩开裂的试验和评价方法,该法能够准确测量约束状态下混凝土干燥收缩时其内部产生的拉应力,特别是能够客观评价补偿收缩混凝土在弹性限制条件下抵御收缩应力的能力;提出了干燥收缩开裂概率C的概念,并将混凝土发生干燥收缩开裂的概率划分为C≥60%(高开裂风险),40%≤C<60%(中等风险)和C<40%(低风险)三种状态;试验表明,补偿收缩混凝土能够在混凝土中建立一定的自应力,可以有效降低混凝土的干燥收缩开裂概率。
3)  Cracking velocity
开裂速率
1.
The failure zone model developed by Schapery is adopted to derive simple mechanical relations for predicting cracking velocity when macro cracks stably propagate in asphalt mixtures.
采用Schapery提出的局部衰坏区模型,推导了沥青混合料宏观裂缝稳定扩展阶段开裂速率的简单力学表达式。
4)  gap-splitting rate
裂离开纤率
1.

从涤/锦复合超细纤维织物上选取纱线做纤维切片,利用光学显微镜观察切片,数码相机拍照,分别计数照片中纤维的移位和裂离开纤率。
5)  opening joint rate

在分析目前卸荷带划分方法的基础上,根据卸荷带的形成机理及地质表现,提出了用裂隙率、张开裂隙率和“隙宽和”3个量化指标进行卸荷带的划分。
