在本文中,我们分析了混合有限元近似对 Reissner-Mindlin 板问题求解的收敛性。我们展示了几个已知的元素属于我们的分析,从而提供了一个统一的方法。我们还引入了一种低阶三角形单元,它在板厚上是最优阶均匀收敛的。
In this paper we analyze the convergence of mixed finite element approximations to the solution of the Reissner-Mindlin plate problem. We show that several known elements fall into our analysis, thus providing a unified approach. We also introduce a low-order triangular element which is optimalorder convergent uniformly in the plate thickness.
