摘要: 本文从理论上比较了四边形四节点元和四边形八节点元的h-收敛性,得出八节点元较四节点元有较快收敛率的结论.并通过算例进行了验证。

Abstract: The present paper is mainly,concerned theoretically with the compartive stuudy on n-convergence of 4-node versus 8-node quadrilateral elements.It is found by the present authors that 8-node quadrilateral elements provided favourably enhances convergence rate over the 4-node ones.The fact is further justified via numerical examinations.
