We study a problem of oscillations of an isotropic inhomogeneous hollow prestressed cylinder under the action of an axisymmetric periodic load. We analyze the amplitude-frequency characteristic depending on prestressed state types in order to identify the frequency ranges most sensitive to the prestress. On the basis of the perturbation method; we derive formulas allowing to find approximately changes in the resonant frequencies caused by the presence of a given inhomogeneous prestress field. We analyze the effect of prestress levels on the change in the cylinder's natural frequencies. © 2020 Elsevier Ltd;
