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.

“…Integration of vibration testing is essential for damage assessment for accurate detection of type and location of damage, but certain challenges still exist in the statistical pattern recognition paradigm process. There are currently many methods, such as acoustic emission [12], electrical impedance [13], vibration-based thermography [14], and wave-guided techniques [15], to detect damage in complex sandwich structures. Damage results in changes to the structure's physical properties, and these changes can be used as a gauge for the overall health of the structure.…”

In this research work, experimental and numerical analyses were conducted to ascertain the impact of damages on modal frequencies of sandwich structure. The structure consists of laminated E/glass epoxy face sheets with [0°/90°]s stacking sequences and polyurethane foam core. The fabrication processes involved are hand layup technique, mold filling process and the use of adhesives to assemble the structure. Damages introduced during fabrication, encompassing core damage, delamination between face sheets and core and impact damage. Experimental modal testing was conducted on four distinct specimens using a Fast Fourier Transform (FFT) analyzer under cantilever boundary conditions. The results reveal significant variations in modal frequencies and mode shapes in the structures. A consistent six-mode frequency bandwidth is observed within the 2000 Hz range across all specimens. The numerical analysis was performed by Finite Element Method (FEM). Experimental and numerical results were in a good agreement. It was observed that modal frequencies decrease due to the presence of damage in the fabricated structures.
