板中孔应变分布规律的实验研究及其应用

Experimental study on strain distributing disciplinarian about the plane with a bore and its application

本文对板中孔孔边应变分布规律的实验方法的可行性进行了论证,并通过实验得到数据,应用格拉布斯 方法对该组数据进行取舍,最后根据有效数据的牛顿插值多项式,得到在一定范围内近似地表示孔边应变系数的表 达式,并且以此结果与弹性力学理论分析结果进行比较,论证该方法结论的可靠性及其应用的灵活性。

The experiment method about strain distributing disciplinarian on the plane with a bore is expatiated . The article brings forward multinomial gained for expressing the strain on the board around the hole with the experiment data and selecting data by Grubbs law. And the conclusion compared with the theoretics result is credibility and its agility.
