| 摘 要： | 本文提出在非协调等参位移元的研究中应该注意到总位移函数在直角坐标下的完备性。根据这一思想,文中针对弹性力学平面问题建立了新的非协调等参位移元模型系列,良好的数值实验结果表明了这一研究思想的合理性。

| Abstract: | It is proposed in the paper that the completeness of displacement functions in physical coordinates deserves consideration in the development of the incompatible finite elements with internal parameters. In this way, three 2D isoparametric incompatible elements with quadratic completeness in Cartesian coordinates have been constructed. They show better stress solutions than those of incompatible ones with the completeness in natural coordinates. |

| Keywords: | incompatible element Cartesian coordinates completeness of trial function |
