The paper presents a calculation method and the results of modeling the nonlinear forced planar oscillations of a beam. The calculation approach is based on the method of weighted residuals in the Galerkin form in combination with numerical methods of integration over time. A sequential analysis of elastic linear and geometrically nonlinear oscillations is performed and the case of irreversible deformation due to the occurrence of physically nonlinear creep strains is considered.
