本文论述了一种用于各向异性弹性板弯曲问题的新型混合杂交有限元方法，该方法对每个三角形内部的弯矩和扭矩张量以及挠度场，以及每个三角形边上的位移场及其法向导数的迹线进行同时逼近。已经为这种混合杂交格式开发了高效的计算机实现程序。给出了针对具有实际和研究价值的不同各向异性板的数值实验结果。
The paper deals with a new mixed-hybrid finite element method for anisotropic elastic plate bending problems, which gives a simultaneous approximation to bending and twisting moment tensor and deflection fields in the interior of each triangle and traces of the displacement field and its normal derivative on sides of each triangle. Efficient computer implementation procedures for this mixed-hybrid scheme have been developed. Results of numerical experiments on different anisotropic plates of practical and research interest are given.
