The variation of mean CT values in small statistic region is more sensitive to the initiationofcrack.
小统计区域平均CT数变化则对裂纹萌生更敏感。

It is investigated that the initiationofcrack in fiber reinforced composites under impact loading by SHTB experimental technology in this paper.
采用SHTB技术对纤维增强复合材料裂纹动态起裂行为进行了实验研究。

As the fleet ages, there's an increasing need for embedded wireless strain sensors capable of detecting and tracking accumulated strains — "precursors" to crackinitiation, according to the official.
