| contents | This paper proposes and analyzes a finite difference method based on compact schemes for the Euler-Bernoulli beam equation with damping terms. The method achieves fourth-order accuracy in space and second-order accuracy in time, while requiring only three spatial grid points within a single compact stencil. Spatial discretization is carried out using a compact finite difference scheme, with a variable substitution technique employed to reduce the order of the equation and effectively handle the damping terms. For the temporal discretization, the Crank-Nicolson scheme is applied. The consistency, stability, and convergence of the proposed method are rigorously proved. Numerical experiments are presented to verify the theoretical results and demonstrate the accuracy and efficiency of the method. |
