fracture strength factor

Also it has been determined that fracture spacing, aquifer strength and skin factor have insignificant effect on water coning in fractured reservoirs.

另外，裂缝间距、蓄水层强度和表皮系数在裂缝型油藏中的水锥现象也起重要作用。

The former two types are brittle ones, and the fracture strain of pyrolytic carbon matrix is the controlling factor of the strength.

前两种为脆性断裂方式，热解炭基体的断裂应变是这类材料强度的控制因素。

Mesoscopic damage size on the top of crack is analysed, the effective stress strength factor is defined, the mode I crack damage fracture criteria is presented.

以混凝土单轴拉压损伤为基础，给出了单元弹性损伤本构关系，分析了裂纹尖端损伤微裂区尺寸，定义了有效应力强度因子，给出了I型裂纹损伤断裂判据。
