平面弹性力学问题各向异性一阶混合元格式

The First Order Anisotropic Mixed Element Scheme of the Plane Elasticity Problems

研究了平面弹性力学问题在各向异性网格下的一阶混合元格式,在不需要引入传统的投影算子的情况下,直接利用插值算子得到了与以往文献相同的误差估计.

The first-order mixed element scheme with the anisotropic meshes of the plane elasticity problems is discussed,The same error estimates as the previous papers are derived by use of interpolation directly,instead of the traditional projection operator.
