The fourthorder Runge-Kutta method is used to transform the mathematics model into discrete simulation model, using MATLAB7.0 simulation software to simulate its dynastic performance.
In this paper, the initial-boundary value problem of a kind of nonlinear fourth-order wave equations with damping and source terms is studied on the base of Beam equation.
