A New Quadrilateral Nonconforming Model and Its Convergence

摘要: 本文给出了一个新的四边形非协调元,利用广义分片检查,对其收敛性进行了研究并给出了应力和位移的误差估计.最后,对弹性力学平面问题做了数值计算.

Abstract: This paper presents a new quadrilateral nonconforming finite element. We deal with its convergence by using generalized patch teat. The error on stresses and displacements are obtained and numerical compulations for plane elastic problems are given.
