摘要
本文运用近年来发展的拟协调元法的基本思想,构造了一个简单有效的四节点四边形的Mindlin板单元.该单元完全控制了W的“时漏模式”(hourglass-mode)对有限元解的影响.数值结果表明该单元实施简单、不缺秩且收敛快.
In the present paper, by utilizing the essental idea of the QuasiConforming method developed aecently, we constsnct a simple and efficient four-node quadrilateral element for the Mindlin plate in whech the i(?)fbuence of the W-hourglass mode on the numerical solutions is controlled quite successfully. The numerical results shows that the present element possessess following properties: simple implemention. rapid convergence and lank sufficiency.
