摘要
本文基于修正的势能泛函,引入适当的广义协调条件,导出了一种具有12个自由度的广义协调板弯曲扇形位移单元GC—S12,这种单元自由度少,列式简单,精度高。
In this paper, based on the modified potential energy functional and by introducing the generalized conforming conditions, a generalized conforming Sector element for thin plate bending with 12 degrees of freedom, GC-S12, is developed. The advantages of this element are.less degrees of freedom, simpler formulas and higher precision.
