摘要
通过对切槽炮孔的切槽参数(切槽深度、张角、锐度)进行的一些模型实验,现场试验及理论分析,得到的结论是:切槽尖端锐度对切槽尖端应力集中系数的影响比其它切槽参数的影响大得多,并且相对切槽深度值应大于0.2。
Some model experiments, Practical testing and theoretical analyses on the notch parameters (notch depth, angle and sharpness) of the notched boreholes have been conducted. The major conclusions are that the sharpnees of a notch is more important effect factor than other notch parameters on coefficient of stress concentration at tip of a notched borehole,and that the relative depthcs of notches must be greater than 0.2.
