采用能量差率方法 ,导出耐久性设计中相对小尺寸孔边角裂纹应力强度因子解析形式的闭合解。根据此方法 ,可充分利用二维结果解决三维问题。
An analytical method of explicit closed form solution of stress intensity factors for three dimensional finite bodies with small corner cracks in durability design is derived by means of the energy release rate method. Hence the two dimensional results of stress intensity factors can be utilized sufficiently to solve the three dimensional problems of stress intensity factors. The results provided by this method are in good agreement with some given by existed methods. So the three dimensional stress intensity factors can be obtained by energy release rate method with high computational efficiency.
