The period function and the Harmonic Balance Method
Bulletin des Sciences Mathématiques, 2015 In this paper we consider several families of potential non-isochronous systems and study their associated period functions. Firstly, we prove some properties of these functions, like their local behavior near the critical point or infinity, or their global monotonicity.

Calculation of nonlinear vibrations of piecewise-linear systems using the shooting method
Vietnam Journal of Mechanics, 2012 In this paper, an explicit formulation of the shooting scheme for computation of multiple periodic attractors of a harmonically excited oscillator which is asymmetric with both stiffness and viscous damping piecewise linearities is derived.

Comments on the method of harmonic balance [PDF]
Journal of Sound and Vibration, 1984 Scientists and engineers are often confronted with a non-linear ordinary differential equation for which physical considerations suggest that one or more types of oscillatory motions are possible. In general, except under very special conditions, exact solutions in closed form do not exist.
