摘要
本文基于位移型Gurtin变分原理，对时间域进行离散时，采用具有非时间步参数的话值函数逼近广义节点位移，给出了一种新的计算弹性动力学初值问题的非时间步参数时间有限元法这是一种无条件稳定的计算格式算例表明，本文方法具有计算方法简便。
A new time finite element method based on Gurtin variational principle of displacement model is presented. The interpolation functions with non -time -step -parameter is introduced to approximate the nodal displacement in time domain. An unconditional stable formula is given. The examples indicate that the algorithm is simple and applicable to the fields of engineering. And also the algorithm gives a satisfying accuracy.
