摘要
本文用变量分离法推导了求解矩形域平面问题的通用应力函数和用该通用应力函数表达的应力分量、应变分量以及位移分量公式。该通用应力函数可用来求解受任意载荷作用的矩形域平面问题。且所得解答不是放松边界条件的圣维南意义下的解答 ,而为精确级数解答。
A general stress function is derivatived to solve rectangular plane problems which are subjected to arbitrary surface loads. Unlike the solution of Savant's in relaxing boundary conditions, the solution obtained by the function is precise and formulated by series.
