| 摘 要： | 本文在N.I.Muskhelishvili关于无限大板受集中力作用问题一般表达式的基础上,导出了用于保角变换的一般表达式。应用一般表达式,并取级数前几项作为变换关系式,获得了几个典型情况的封闭解,利用这些封闭解分析了胶贴的效果。

| Abstract: | Based on the general formulas of N.I.Muskhelishvili about a plate under concentrated loads, the more generalized formulas with arbitrary transform function, Z = ω(ξ), were derived. By these formulas and a few terms of the transform function,the problems of infinite plate with a hole and finite plate with arbitrary outside bounds were solved in closed form. These results were applied to analysing the problem of the damaged plate reinforced by all kinds of glued patchs. |
