摘要 借助弯折裂纹位错模型的奇异积分方程方法研究含圆孔无限大域中孔边弯折裂纹问题.利用数值积分公式求解相应的方程,并结合位错密度得到弯折裂纹尖端处的应力强度因子值.此方法可使用于更加复杂的裂纹问题. The edge bending crack problems are investigated using the singular integral equation ap- proach. The solution was made using the singular integral equations. The stress intensity factors at the crack tips were obtained. The proposed method can be used for more complex crack problems.
