“…In the paper [148], the displacement-based refined zig-zag theory (RZT) was used for the first time to determine the dynamic characteristics of composite sandwich plates made from elastic and VE layers. This was a development of the approach proposed in [149] by the same authors, and was devised to analyze the layered beams. The use of RZT allowed the introduction of an efficient and simple description of the layered structures' kinematics.…”

“…In [259], dynamic characteristics of frames with built-in VE dampers were determined, and in [122], the influence of temperature was additionally taken into account. In the papers [149,177], beams with VE layers were analyzed; [260] reported the results for plates with VE layers, and in [261], reticulated domes built from composite elastic/VE rods were studied. In the continuation method, the initial solution is known and derived from solving the eigenvalue problem for the undamped system.…”

The paper is devoted to a review of recent achievements in the field of dynamic analysis of structures and structural elements, such as beams and plates, with embedded viscoelastic (VE) dampers and/or layers. The general characteristics of VE materials, their rheological models, and methods of parameters identification are discussed. New formulations of dynamic problems for systems with VE elements are also reviewed. The methods of determination of dynamic characteristics, together with the methods of analysis of steady-state and transient vibrations of such systems, are also discussed. Both linear and geometrically non-linear vibrations are considered. The paper ends with a review of the methods of sensitivity and uncertainty analysis, and the methods of optimization, for structures with VE elements.

“…Such laminates need long processing durations at high temperatures and pressures in autoclaves, producing good quality (no void content) and a high fiber volume fraction [31][32][33][34][35][36][37]. Various methods to analyze the free vibration problems of layered beams, plates, and shells have been described in numerous papers; for example, Roman Lewandowski et al (2021) conducted numerical studies on dynamic characteristics for composite sandwich beams made from elastic and viscoelastic layers based on refined zig-zag theory [38]. Vibration behaviors of a composite plate resting on the nonlinear elastic foundation using the finite element method are also discussed in [39].…”

The main novelty of the paper is that analytical, experimental, and numerical analyses are used to investigate the free vibration problem of a sandwich structure in which Nanocomposites skins (SiO2/epoxy and Al2O3/epoxy) at different densities are used as the face sheet. The volume fraction's of nanoparticle addition varies (0% to 2.5%). The present free vibration was derived based on Kirchhoff's theory and aspiration to obtain the natural frequency. The results show that in structures with SiO2 nanoparticles with a density of 1180 kg⁄m 3, the optimum increase (VF = 2.5%) is 50% in Young's modulus and 22% in natural frequency, while at a density of 1210 kg⁄m 3 is 56 % in Young's modulus and 24.5% in natural frequency. Furthermore, the same structures reinforced with Al2O3 Nano-particles show that at the density of 1180 kg⁄m 3 , the optimum (VF=2.5%) parentage increase in Young's modulus is 41% and 19% in natural frequency, while at the density of 1210 kg⁄m 3 is 46% in Young's modulus and 21% in natural frequency. A numerical investigation was used to validate the obtained results of the analytical solution. The findings also show an acceptable convergence between analytical and numerical techniques with a maximum discrepancy not exceeding 3%.
