摘要
在弯扭载荷作用下,研究线弹性各向异性纤维复合材料板裂纹尖端附近的应力场、位移场。利用复变函数方法,选取带参数的挠度函数作为控制方程的解,借助边界条件,确定未知参数,得到满足偏微分方程边值问题的解,从而推出裂纹尖端附近的应力和位移计算公式。所得到的公式在有关的断裂分析中有重要的参考作用。
The stress and deformation distributions near crack tip for linear elastic anisotropic composite plate under bending and twisting loads were analyzed.Complex function method and the deflection function with parameters are chosen to define the unknown parameters with the aid of boundary conditions,thus we can get the solutions to the boundary value problem of partial differential equation,and then the expressions for stress and displacement near crack tip are derived.All the derived equations are very important to fracture analysis of composite structures.
