一、概述文克尔地基板的有限单元方法,是将板分成矩形单元,单元间通过结点互相连结。程序中采用的是位移法,其位移模式为:w=α_1+α_2x+α_3y+α_4x~2+α_5xy+α_6y~2+α_7yx~3α_8x~2y+α_9xy~2α_(10)y~3α_(11)x~3y+α_(12)xy~3
An overview of the finite element method of the Winkel base plate is to divide the plate into rectangular elements, and the elements are connected to each other through the nodes. The displacement method is used in the program. The displacement mode is: w=α_1+α_2x+α_3y+α_4x~2+α_5xy+α_6y~2+α_7yx~3α_8x~2y+α_9xy~2α_(10)y~3α_(11)x ~3y+α_(12)xy~3
