Abstract : The general approach to nonlinear free vibration of elastic structures recently presented by Rehfield is extended in this report to the case of forced vibration. It is assumed that the structure is excited by a disturbing force which is a harmonic function of time and is spatially distributed so as to excite only a single mode. General results are presented along with applications to the vibration of beams and rectangular plates. Other solution methods are compared with the general theory for the beam and the results are found to be in complete agreement. (Author)
