摘要
研究了粘弹性方程的一个新的二阶非协调元的收敛性,利用该单元的特殊性质,在不需要Ritz投影条件下给出了相应的误差估计.
In this paper,the convergence analysis for the viscoelasticity equation with a new second order nonconforming finite element is discussed.By using the special properties of the new element,the corresponding error estimates are obtained without Ritz projection.
