摘　　要：由于孔的存在,必然降低结构的强度。因此,对含孔板应力场进行准确的分析是非常必要的,特别是含孔复合材料板在压缩荷载作用下的应力分析更为重要。对于含圆孔的复合材料板,文中运用复变函数理论中保角映射的方法解决了边界条件问题;采用所建立的数学模型对含圆孔的复合材料板在不同方向压缩荷载作用下进行了较为全面的应力仿真分析;对不同情况下孔边应力分布进行了比较。The strength of structure must be decreased, due to existence of hole. So, it is necessary to calculate the stress field of plate with hole, specially, the stress of composite material plate with hole under compression load. To composite material plate with round hole, the boundary condition problem was solved with conformal mapping in complex variable function. With the established mathematic model, stress analysis of composite material plate with round hole under compression load in different direction was performed. Moreover, the comparison of hole-edge stress distribution under different situation was carried out.
