| 摘 要： | 本文采用边界配置方法计算了受集中载荷作用时椭圆盘中偏心裂纹两端的应力强度因子,其中包括椭圆两半轴不同比值。不同裂纹长度和不同偏心程度的情况,在其特例椭圆盘中心裂纹情形,本文结果与Isida一致;在圆盘偏心裂纹情形,本文给出比Rooke等人更好的结果。

| Abstract: | In this paper, boundary collocation method is used to calculate the stress intensity factors for an eccentric crack in an elliptical disc subjected to two tensile forces. Different cases have been studied, such as discs with different ratios of two axes or varying crack lengths, crack of different eccentric extent. For the particular case of elliptical disc with a central crack, the present results agree very well with those by Isida. On the other side, for a circular disc with an eccentric crack the present results are better than those by Rooke et al, The practice shows that the method has the advantages in simplicity, efficiency and accuracy. |
