| Abstract: | Based on Gurtin variational principle,a spline finite element method for initial value problems of plate was presented by applying spline finite element method to space domain and step by step method to time domain.Numerical results show that higher accuracy can be obtained by using the present methods than the original methods for dynamic responses. |
