摘要
利用样条函数在同一区域上的变异,建立半解析样条元位移场函数。利用元外结线有效减少了总的未知变量,并且使样条元之间的连接保持充分的光滑性。同时利用特定的样条坐标矩阵避免了样条函数在支承处的线性组合。
This paper makes use of the different type of spline function in the same domain to make the displacement function of the semi-analytical spline element.With the outer nodal lines, the unknown coefficients are reduced,and the conjuncion of the adjoining elements is smooth.Meanwhile,the linear-combination of the spline function is avoided with the help of special spline coordinate matrix.
