Periodic Solutions for Some Strongly Nonlinear Oscillators by He's Energy Balance Method
In this paper, applying He-s energy balance method to determine frequency formulation relations of nonlinear oscillators with discontinuous term or fractional potential. By calculation and computer simulations, compared with the exact solutions show that the results obtained are of high accuracy.
