Determination of Approximate Periods of Duffing-harmonic Oscillator
We introduced an analytical technique based on harmonic balance method (HBM) to determine approximate periods of a nonlinear Duffing-harmonic oscillator. Generally, a set of nonlinear algebraic equations are appeared when HBM is formulated.

Validation of Friction Model Parameters Identified Using the IHB Method Using Finite Element Method
A hybrid friction model was recently developed by Azizian and Mureithi (2013) to simulate the friction behavior of tube-support interaction. However, identification and validation of the model parameters remains unresolved. In previous work, the friction

Comments on the method of harmonic balance [PDF]
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.

On the development of a harmonic balance method for aeroelastic analysis [PDF]
To efficiently simulate time-periodic, non-linear flows in turbomachinery a Harmonic Balance (HB) method has recently been developed within the framework of DLR’s compressible, Unsteady Reynolds Averaged Navier- tokes (URANS) solver TRACE.
