摘要
将多复变量应力函数和边界配点法相结合 ,计算含有任意多个椭圆孔无限大弹性板的应力场 .每个孔的大小、位置为任意 ,孔边为应力边界、位移边界和多种混合边界 .板的无限远处作用有和坐标轴方向一致的均匀拉压载荷和均匀剪切载荷 .编制了相应的FORTRAN90程序 ,进行了考题和算例分析 .结果表明 ,本方法行之有效 ,程序使用简单 ,便于应用 .
The stress functions of multiple complex variables are combined with the boundary collocation and least squares method to calculate the stress field of an elastic infinite plate with multiple elliptical holes whose sizes and locations are arbitrary. The boundaries of the holes can be stress, displacement, and many types of combined boundaries. The corresponding FORTRAN90 program is developed, and examples are given. The results show that this method is very effective and convenient. The program can be used easily by engineers
