| Abstract: | The paper proposes a method to analyze forced vibrations in nonlinear systems. The procedure combines Rauscher’s method and Pierre–Shaw nonlinear modes. Results from an analysis of the forced vibrations of a shallow arch are presented as an example Translated from Prikladnaya Mekhanika, Vol. 44, No. 12, pp. 102–110, December 2008. |
