摘要
本文就弹性问题给出了一个稳定化组合杂交有限元方法。此方法可以看作是周天孝对此问题提出的组合杂交格式的一个发展,即结合稳定化有限元法思想,对组合杂交方法进行改进,增加了一个边界稳定项,既避免了B-B条件,去掉了"能量优化"条件的要求,又具有很好的稳定性及误差估计。
This paper introduces a stabilized hybrid finite element method on elasticity problem, and this method could be viewed as a new development of hybrid finite element method presented by Zhou Tianxiao. This approach combines the stabilization of finite element method, improves hybrid finite elemert method, and adds a jump of displacement on edges, which could avoid the inf- sup condition and the energy compatibility. The theoretical analysis shows that this method has better stability and error estimate.
