摘要
作者提出了一种带旋转自由度的四边形组合杂交元.该元采用Allman插值与分片常应力.数值实验表明该元具有较好的精度.
A combined hybrid quadrilateral finite element with drilling degrees of freedom is proposed. Allman's displacement interpolation and piecewise constant stress mode are used. Numerical experiments show that the method is of good accuracy.
