چکیده
The purpose of this paper is to study the axisymmetric vibrations circular three-layered sandwich plates with a frequency-dependent fractional viscoelastic core and elastic face sheets. First, equations motion related boundary conditions are derived using Hamilton’s principle for free vibrations. Then, governing obtained various solved parametric studies carried out examine vibration behavior core. differential transform method (DTM), well-known semi-analytical–numerical solution technique, utilized eigenvalue analysis. In addition, finite element (FE) commercial code ANSYS added comparison. effect layer thicknesses location material on dynamic damping characteristics derivative studied in detail.
