摘要
采用复变函数方法,通过将裂纹尖端的应力和位移代入J-积分的一般公式,推出了各向异性纤维复合材料单层板I型裂纹尖端J-积分的复形式-复变函数积分的实部,证明了该J-积分的路径无关性,得到了它的具体计算公式.
By using a complex function method, the complex form of mode I crack tip Jintegral for linear elastic anisotropic fiber composite plate is deducted. The pathindependent of this Jintegral is proved. The concrete computing formula of this Jintegral is obtained. The derived results are important in fracture analysis.
