| 中文摘要: |
| 本文从三次平面等参元出发，构造出角结点有旋转自由度的三角形单元。该单元与三次平面等参元有相同的单元特征及精度，同时具有连续介质力学中关于旋转度的定义。 |
| 英文摘要: |
| A new plane triangular element with rotational degree of freedom at each corner is con- formed from ten-node isoparametric element in this paper. The character and precision of the new element are the same as those of isoparametric element , the rotational definition of the new element are the same as those of isoparametric element , as the rotational definition of the new element is the same as that of continuum mechanics. |
