摘要
讨论了一种二阶椭圆问题的修正Morley元方法.通过引入投影算子,构造了修正Morley元的离散有限元方法,并给出了该方法的能量模估计和低模估计.
This paper probes into a modified Morley element method for the second-order elliptic problem. A discrete finite element method with modified Morley element is formally constructed via the introduction of the projection operator. Finally, the optimal error estimates in the energy norm and L^2 norm are derived.
