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。
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.
