摘要
本文中分析了线弹性问题的一种局部稳定化的混合有限元方法，引入了一种“宏元条件”。当该条件被满足时，我们对Ｑ１－Ｐ０四边形单元和Ｐ１－Ｐ０三角形单元得到了该方法关于可压缩性一致的误差估计。
Abstract In this paper,a locally stabilized finite element formulation of the linear elasticity problem is analyzed.A macroelement condition is introduced. By satisfying this condition,we give uniform error estimation with respect to the compressibility for the Qi-P0 quadrilateral and the P1-P0 trianglar element.
