fracture direction meaning in Chinese
裂缝方向
Examples
- Research on several facture mechanism and macro - fracture direction in several types of alloy steels
几种合金钢断裂机理与宏观断裂方向的研究 - After analyzing 8 layers test data in 6 wells , we get the reservoir parameters of the nature fractured reservoir and the composite reservoir and the main fracture direction in this region
经对该区6口井8层试井资料分析，得到裂缝型油藏(包括宽而长的裂缝型油藏、压裂后形成长裂缝型油藏)及复合型油藏参数，并确定了该区的主裂缝。 - It ' s indirectly proved that the oriented method is a reliable and practical . moreover , the natural fracture direction tested by the underground microseismic monitoring system also proved that the orientation technique is correct and comparable . 6
同时，针对该试验区块，对两口开发井进行了地下微地震波监测，测得的人工裂缝方位与实验测得的最大主地应力方向非常吻合，进一步证明了该方法的正确性和可比性。 - The thesis studied the change of stress triaxiality in the four - point curved beam made in 16mnr with arc - tip crack and its important effect . in the beam , the points of peak value of stress triaxiality distribute along a line , whose direction is well consistent with the fracture direction got by experiment when so > 3mm
在圆弧裂纹试件中，裂尖附近的三轴度较高的点呈脊线分布，按照脊线分布拟合计算得到的三轴度脊线夹角在偏心距so 3mm时与试验测得的断裂角符合较好，这种情况下试件发生的是韧窝型断裂。 - Based on lots of experiments , by combining the progress in mesomechanics with fea computation and analysis , this thesis investigated many parameters " effect on crack with an arc - tip in plain mixed - mode fracture , and compared existing criteria for fracture initiation , fracture direction and fracture mode transition
本文主要的工作是在试验的基础上，结合细观断裂力学当前的研究进展，通过有限元计算和模拟分析，研究了平面复合型断裂中各种力学参量对圆弧尖端裂纹断裂的影响，比较分析了现有的起裂判据、断裂扩展方向的判定方法以及断裂模式的转换条件。
