九参广义协调元的误差估计

Errorestimate of nine parameter generalized conforming element

九参数广义协调元是板弯曲问题收敛性很好的有限元.以往文献中仅证明了它的收敛性,本文给出它的误差估计式,并分析了节点参数的扰动量.

The nine parameter generalized conforming element is an effective element for the plate bending problem.However,the former papers prove only the convergence.The aim of this article is to obtain its error estimates.Furthermore,the pertubation of the nodal parameters are also analysized.
