摘要
用组合杂交方法对Zienikiewicz三角板元进行了改进.弯矩采用分片常数逼近.三种不同网格剖分下的数值实验表明Zienkiewicz元的组合杂交改进可以达到粗网格高精度.
Improvement of Zienkiewicz triangular element by combined hybrid finite element methods is used.The piecewise constant bending moment mode is adopted.Numerical experiments at three different meshes show that the combined hybrid counterpart of Zienkiewicz's element is capable of attaining high accuracy at coarse meshes.
