The response of non-linearities to a sum of commensurate or incommensurate sinusoids is considered," several efficient computational methods are presented. As a special case the M.LD.F. is derived, and applications to subharmonic response are given.

## Abstract This paper presents a new appoach based on the use of describing functions to obtain approximate symbolic expressions for the fundamental frequency component as well as for the secondβ and thirdβorder harmonics. A single soft or hard transconductance nonβlinearity embedded in an arbitra
The steady state, geometrically non-linear, periodic vibration of rectangular thin plates under harmonic external excitations, is analyzed using the hierarchical "nite element and the harmonic balance methods. Modal coupling due to internal resonance is detected and the consequent multi-modal and mu
