The nonlocal Euler-Bernoulli beam model has been used for the continuum modeling of the nanobeam structure. This problem leads to a time-dependent Mathieu-Hill equation and has been solved by using the Lindstedt-Poincare perturbation expansion method. The effect of a small-scale parameter on the dynamic displacement and critical dynamic buckling load of nanobeams has been investigated. Stability regions have been obtained from the local and nonlocal elasticity theories. The effect of the longitudinal vibration of nanobeams on instability regions has been included in the present analysis. Amplitudes of an arbitrary point of a nanobeam due to harmonic loads have been determined. Nonlocal and longitudinal vibration effects reduce the area of the instability region and increase amplitudes.en10.1177/1077546318802430info:eu-repo/semantics/closedAccessDynamic BucklingNanobeamsInstability RegionPerturbationNonlocal ElasticityWalled Carbon NanotubesNonlocal ElasticityBuckling AnalysisVibrationBearingModelsArticle254820833Q2WOS:0004565348000082-s2.0-85060595504Q2
