摘要
研究了正方形夹杂角部的奇异应力场 .该应力场由分别对应对称变形和反对称变形的两组独立奇异应力场组成 .应用体积力法计算了正方形夹杂角部的广义应力强度因子 ,并讨论了两个正方形夹杂之间距离对广义力强度因子的影响 .
The fileds of singular stress naer the corners of square inclusions are investigated. The singular stress fields appear to be two independent singular stress fields, respectively corresponding to symmetric and skew symmetric deformations. The generalized stress intensity factors near the inclusion corners are calculated by using body force method. The influence of the distance between the two square inclusions on the generalized stress intensity factors is also calculated.
