deep crack

There was a deep crack in the ceiling above him .

在他头顶的天花板上有一道很深的裂缝。

The results show that the revised formula is consistent with the primary formula for the deep crack problems .

结果表明，对深裂纹问题，修正后的计算公式与原有的单一材料结论吻合较好。

On the basis of systemically and thoroughly studying geology and environment foundation of the deep crack , this paper has established the formation mechanism of deep crack .

在系统深入地研究瀑布沟水电站库首右岸深部裂缝和深溪沟水电站坝区右岸岸坡深部裂缝的地质和岩体力学环境基础上，建立深部裂缝的力学机制类型。

But for the Non-Destructive Testing ( NDT ) of crack , actually appears in particular to the deep crack tradition detective method is helplessly .

但是裂缝的无损检测，尤其是对较深裂缝的深度检测传统的检测方法却显得无能为力。

Different types of deep crack have different meaning to slope stability . So , it is important to distinguish the type of deep crack and analyze the formation mechanism of deep fracture in exploring and studying large slope of hydropower station .

不同斜坡深部裂缝类型对斜坡稳定具有不同的意义，因此，甄别斜坡深部裂缝类型，分析其形成机制，一直是大型水电工程边坡勘测研究中的一项重要内容。

Finite element method was used to analyze the J integral evaluation method for a cylindrical specimen with deep circumferential crack under axial or torsional load .

通过有限元解析方法分别研究了轴向或扭转载荷下带环状裂纹圆棒试样的J积分的评价方法。

In the present paper , the J integral was estimated from the relation between torque and twist angle of a cylindrical bar with a deep circumferential crack .

研究了扭转载荷下带环状裂纹圆棒试样的J积分的评价。

Cohesive zone sizes of deep type ⅰ crack were calculated assuming that cohesive force is constant .

在常值的内聚力假定下，计算了Ⅰ型深裂纹的凝合区尺寸。

Finally , a formula of the single-point method for computing the J-integral is suggested , which may be applied to samples of fracture toughness with either deep or shallow crack .

最后，提出了单点法J积分计算公式.这个公式既适用于深裂纹的断裂韧度试样，也适用于浅裂纹试样。
