摘要:

该文给出弹性力学问题的混合有限元法及其整体估计.该方法不受经典的B.-B.条件约束.因此,其有限元空间可以自由地选择,并得到最优的误差估计

关键词: 弹性力学问题 , 整体估计 , 混合有限元

Abstract:

In this paper a least-squares mixed finite element  methord for elasticity problems is presented and teh global estimates of mixed finite element solution are derived. The method is not object to teh classical B.-B.condition so that teh finite element space may be selected freely and optimal error estimates can be obtained.

Key words: Elasticity problems, Global estimates, mixed finite element
