Modified multiple time scale method for solving strongly nonlinear damped forced vibration systems
In this paper, modified multiple time scale (MTS) method is employed to solve strongly nonlinear forced vibration systems. The first-order approximation is only considered in order to avoid complexicity.

Effects of Nonlinear Damping on Vibrations of Microbeam
The present paper develops a new Bernoulli–Euler theory of microbeams for the consideration of small-scale effects and nonlinear terms, which are induced by the axial elongation of the beam and Kelvin–Voigt damping.

Nonlinear Torsional Vibration of Size-Dependent Functionally Graded Rods [PDF]
This study aims to investigate the effect of functionally graded materials (FGMs) on the internal resonances of nanorods in torsional vibration. The von-Kármán type nonlinearity is considered and the governing equation of motion is derived using Hamilton'

Method of multiple scales with three time scales [PDF]
AbstractSome confusion appears in the literature regarding the extension of the method of multiple scales to three or more time scales. While the work of Murdock and Wang [1] correctly indicates some obstructions to such an extension in some types of problems, other work suggests that the extension should almost never be possible [2]. These pessimistic

In this work, a mode parabolic equation method with interacting modes accounting for the weak elasticity at the bottom is developed. An important feature of the proposed method is that computations of elastic modes are avoided and that the solution is ...
