摘要
本文提出了一种适用于杂交/混合有限元的算法.从单元柔度矩阵到单元刚度矩阵的计算中.能做到既节省内存,又减少运算量,并具体地给出了所需运算量的估算式.
An algorithm suitable for hybrid/mixed finite elements is proposed.The element stiffness matrix is derived from the element flexibility matrix and,by this operation,not only the computer storage is saved,but also the calculation load is diminished.Besides,the formula needed for calculation is presented.
