This paper treats the mixed finite element methods for second order nonlinear hyperbolic equations. Existence and uniqueness of the solution of the discrete problem are proved. A priori error estimates for optimal order L ∞ in space are derived for both displacement and stress. Results are given for the continuous time case.

This paper discuss the bicubic spline element solution for plate problem, we obtain the superconvergence result with two order higher than ordinary accuracy,***, we get the asympototic expansion and superconvergence result of the first and second derivatives. A combination formula of the second derivative which have the accuracy of O(h4) is also derived.
