Abstract
This paper is concerned with the numerical approximation of the solution of the coupled wave equation of Kirchhoff type with nonlinear boundary damping and memory term using a mixed finite element method. The Raviart‐Thomas mixed finite element method is one of the most prominent techniques to discretize the second‐order wave equations; therefore, we apply this scheme for space discretization. Furthermore, an L2‐in‐space error estimate is presented for this mixed finite element approximation. Finally, the efficiency of the method is verified by a numerical example.
