摘要
本文证明了不完全双二次非协调板元离散的 Poincaré型不等式成立,利用它建立了类似于文的引理,从而由此讨论了边界固支薄板弯曲障碍问题和带平均曲率型约束问题的不完全双二次非协调板元逼近,得到了离散解对真解的收敛性并讨论了离散问题的迭代解。
We prove the discret poincaréinequality of the incomplete biquadratic nonconforming plate element in this paper,first,and then we discuss the approximation of the incomplete biquadratic nonconforming plate element of the obtacle problem and problem with mean curvature restrain for clamped thin phate,whose connergence has been proved.
