The core of this article is to explore the superconvergent behavior of a new second order linearized energy-conserving leap-frog fully discrete scheme without any constraint between the spatial grid size h and the temporal step τ and for nonlinear wave equation. First of all, the considered scheme is rigorously established with nonconforming finite element by use of scalar auxiliary variable (SAV) method. Then, the numerical solution is strictly demonstrated to be bounded in the broken H1-norm, which, combined with the particular characteristics of element and economical interpolation post-processing technique, may directly lead to the unconditional superclose and superconvergent outcomes with orders , without requiring the temporal-spatial error separation approach. Ultimately, comprehensive computational tests are conducted to validate the analytical outcomes and highlight the exceptional performance of the presented method.
