摘要
用非解析开拓数学方法建立平面弹性薄板弯曲问题理论中具有间接变量的等价边界积分方程 ,并采用变分法进行了严格的说明· 以往出现的三种间接变量边界积分方程 ,它们都不是等价的 ,对此我们进行了深入的讨论·
Equivalent Boundary Integral Equations (EBIE) with indirect unknowns for thin elastic plate bending theory, which is equivalent to the original boundary value problem, is established rigorously by mathematical technique of non_analytic continuation and is fully proved by means of the variational principle. The previous three kinds of boundary integral equations with indirect unknowns are discussed thoroughly and it is shown that all previous results are not EBIE.
