摘要
复合材料层板的直边和圆孔自由边缘效应的三维应力分析,国内外已有不少的数值解和近似解析解。Rybicki等提出了各向异性板椭圆孔2维问题变换为圆孔问题的方法,本文论证了这种变换方法的3维情形,从而可根据圆孔自由边缘效应结果来估计椭圆孔自由边缘效应。
According to a method for transforming a three dimensional problem of a single elliptical hole in an anisotropic material to a problem of a circular hole in a different anisotropic material, we can treat the first boundary value problems in a laminate with an elliptical hole especially its free edge effect, if the problem with a circular hole has been solved.
