Abstract
This paper presents the use of different finite schemes to find the approximatednumerical solutions of the initial-boundary-value problem involving the linear and nonlinear damped equations of a suspended string. The results are compared with the suspended string without a damping term provided that the initial shape and velocities are all the same. The results show that the vibration amplitude decreases and the vibration pattern demonstrated is quite different from the initial pattern in the nonlinear damping case. The vibration amplitude also decreases in the linear damping case but the initial vibration pattern is still maintained. The results are compared graphically and also summarized in Tables. In addition, we find that the coeff icient of the damping term plays a role in determining the vibration amplitude.
