摘要
对正交异性复合材料板的Ⅱ型裂纹尖端应力场进行了有关的力学分析,通过求解一类线性偏微分方程的边值问题,引入新的应力函数、采用复变函数方法推出了正交异性复合材料板Ⅱ型裂纹尖端附近的应力场的计算公式.
Mode- Ⅱ stress field near crack tip of fiber reinforced orthotropic composite materials is analYzed. The boundary value problem of one kind of partial differential equation is solved. By introducing new special stress function and using complex function method, the stress field theoretical computing formulae of mode- Ⅱ crack near crack tip are obtained.
