| Abstract: | This paper reviews the developments of the spline finite element method based on the variational principle, the theory of spline function and the state space theory during the last twenty years. It includes the application of cut spline function in mechanics, as an early development, the advantages and disadvantages of spline finite element, spline finite point and spline element, the application of multivariable spline finite element method and spline state variable method in dynamic response. |
