Application of Modified Homotopy Perturbation Method and Variational Iteration Method to a nonlinear oscillation problem abstract
In this paper, we use Modified Homotopy Perturbation Method (MHPM) and Variational Iteration Method which are powerful methods with simple procedures, to determine theperiodic solutions for the equation of motion for a mass attached to the center of a stretched elastic wire in dimensionless form which is example of a conservative nonlinear oscillatory system having an irrational elastic force. The solution procedure is simple, and in comparison with exact solution, that the result obtained is valid with high accuracy.
