Research highlights► The harmonic balance method is adopted to study the nonlinear vibrations of MWCNTs. ► The influence of nonlocality on the nonlinear vibrations of MWCNTs is examined. ► In the nonlinear regime, the vdW interaction between all layers of MWCNTs must be included. ► At high temperatures, the nonlinear frequency ratio is higher than that of the zero temperature. ► At low temperature, however, this frequency ratio is lower than that of the zero temperature. Graphical AbstractA nonlocal Timoshenko beam model is developed to analytically study the nonlinear vibrations of embedded multiwalled carbon nanotubes (MWCNTs) in thermal environments.
