A concept named modified or generalized simply supported edges is therefore introduced , i . e . , superimposing altogether the solutions to the rectangular plate with four simply supported edges on which the uniformly distributed load locally acts , to the rectangular plate with four simply supported edges of which one of them is under the action of distributed bending moment and to the rectangular plate with various generalized simple supported edges and then taking the continuity condition of boundary , so as to let the result of superimposition satisfies all boundary conditions , an analytic solution is given to the rectangular overhanging plates on which any kinds of loads are acting 使用了變相的或廣義簡支邊的概念,將四周簡支局部作用分布載荷矩形板的解、四周簡支一邊作用分布彎矩矩形板的解及各種具有廣義簡支邊的矩形板的解進(jìn)行疊加,并應(yīng)用邊界連續(xù)性條件,令這樣的解滿足所有邊界條件,得到了任意載荷作用下矩形外伸板的解析解。
