The results show that G_(fF),critical crack mouth opening displacement(δ_(fmc)) as well as critical crack tip opening displacement(δ_(ftc)) of SFHAC increase linearly with the increas.
结果表明:随着φf的增加,GfF、临界裂缝嘴张开位移(fδmc)、临界裂缝尖端张开位移fδtc均线性增加,钢纤维高强混凝土断裂能增益比、临界裂缝嘴张开位移和临界裂缝尖端张开位移的增益比亦基本呈线性增加。

In order to investigate the size effect of the fracture toughness of concrete,the size effect law deduced from Weibull s statistical theory was compared with that from Bazant s energy release principle,and three fracture parameters,namely,the initiatial fraction toughness(Kini1c),the unstable toughness(Kun1c) and the critical crack tip opening displacement(δc) were tested.
为研究混凝土断裂韧度的尺寸效应,将基于Weibull统计理论的尺度律与基于Bazant能量释放原理的尺度律进行对比,进行了3种混凝土断裂韧度,即起裂韧度Ki1nci、失稳韧度Ku1nc及临界裂缝尖端张开位移δc的试验研究。
3) Critical crack tip opening displacement CTODc
临界裂缝尖端开口位移
4) rack tip opening displacement
裂缝尖端张开位移
1.
It is difficult to measure the crack tip opening displacement(CTOD) of a concrete dam because the subcritical propagation of the crack often occurs before the fracture does.
由于混凝土坝裂缝在失稳扩展前常发生亚临界扩展,难以测量混凝土坝裂缝尖端张开位移,且通过试验获得稳定的临界裂缝尖端张开位移比较困难,因此不能直接应用裂缝尖端张开位移理论分析混凝土坝裂缝失稳扩展。
5) fracture tip
裂缝端部
1.
Based on fracture mechanics and plastic mechanics,the plastic area at fracture tip in hydraulic fracture propagation is studied.
以断裂力学和塑性力学理论为基础,对水力裂缝端部在延伸过程中的塑性区进行了研究,并据此对地层岩石中水力裂缝附近的塑性区的范围进行了定量研究,同时,对塑性区内断裂韧性的变化对水力裂缝几何尺寸的影响进行了研究,这对水力压裂设计及压裂压力分析等具有指导意义。
6) crack adjacent to anchor
锚端裂缝
补充资料：穿晶开裂
分子式：
CAS号：
性质：金属材料开裂的金属学特征之一。裂纹由晶粒内部穿过。延性断裂的断口微观特征一般为韧窝状，脆性断裂的特征为解理或准解理花样。
