摘要
构造了一种求解有限元动态方程的稳定的差分格式,并将其成功地应用于求解结构振动问题,这种差分方法对求解有限元动态方程是有效的。
In this paper,the stable difference schemes for solving finite element dynamics equations are constructed and successfully applied to the calculation of structural vibration problems.This difference method is effictive in the solvation of finite element dynamics equations.
