摘要
以Ｇｕｒｔｉｎ变分原理为基础，对时间和空间同时离散，建立了一种求解板的动力学初值问题的有限元法，即时空有限元．算例表明，该法计算精度高，稳定性、收敛性好．
Based on Gurtin variational principle, a finite element method called the “space time finite element ” is developed to solve plate bending dynamic initial value problem. The numerical results show that this method has higher accuracy and better stability and convergence.
