“…To enrich the kinematics, Kapuria et al [29][30][31][32] introduced in the above works the well-known zigzag theory. Interesting contributions to the field were also made by Boudaoud et al [33], Belouettar et al [3] and Azrar et al [34], among others. Moreover, the Carrera Unified Formulation (CUF) models for piezoelectric plates were proposed in Ballhause et al [35] as well as in Robaldo et al [36].…”

In this paper, hexahedral piezoelectric solid-shell finite element formulations, with linear and quadratic interpolation, denoted by SHB8PSE and SHB20E, respectively, are proposed for the modeling of piezoelectric sandwich structures. Compared to conventional solid and shell elements, the solid-shell concept reveals to be very attractive, due to a number of well-established advantages and computational capabilities. More specifically, the present study is devoted to the modeling and analysis of multilayer structures that incorporate piezoelectric materials in the form of layers or patches. The interest in this solid-shell approach is shown through a set of selective and representative benchmark problems. These include numerical tests applied to various configurations of beam, plate and shell structures, both in static and vibration analysis. The results yielded by the proposed formulations are compared with those given by state-of-the-art piezoelectric elements available in ABAQUS; in particular, the C3D20E quadratic hexahedral finite element with piezoelectric degrees of freedom.

“…They performed numerical simulations of structures with feedback, adaptive feedback, and hybrid control systems. Boudaoud et al [16] proposed an analytical method for the damping analysis of sandwich beams with piezoelectric and viscoelastic layers, providing an analytical expression for damping analysis. Kumar and Singh [17] made different samples of beams with ACLD and PCLD treatments to investigate the ACLD and PCLD patch positions and coverage by experiment.…”

This paper uses high-order approximate coupling (HOAC) dynamics equations for the hub–beam system with segmented active constrained layer damping treatment (SACLD). To improve the damping characteristics of traditional active constrained layer damping (ACLD), the viscoelastic damping layer, and the piezoelectric constraining layer are cut at the same position. The damping characteristics of the structure are enhanced by increasing the shear strain of the viscoelastic damping layer. The finite element method is used to discretize the SACLD beam. The discontinuity of the SACLD beam element-to-element displacement achieves the notch. Based on the theory of rigid–flexible coupling dynamics, the dynamic responses of the SACLD rotating beam under different cases are studied. The results show that the segmentation method is not always effective. A SACLD beam provides better vibration suppression than an ACLD beam only when appropriate material and dimensional parameters are used. The influences of base-layer thickness, piezoelectric constraining layer thickness, viscoelastic damping-layer thickness, angular velocity, the viscoelastic damping-layer loss factor, and control gains on the vibration of the rotating flexible beam with SACLD treatment are also discussed.

“…Since 1959 and the work of Kerwin [1], an intensive research work was devoted to this type of structures. Initially, analytical methods were developed to yield approximate damping properties (i.e., modal loss factor and natural frequency) of sandwich beam and plate structures with simple boundary conditions [2][3][4].…”

This work deals with the vibration of orthotropic multilayer sandwich structures with viscoelastic core. A finite element model is derived from a classical zigzag model with shear deformation in the viscoelastic layer. The aim of the present work is to establish numerical models and develop numerical tools to design multilayer composites structures with high damping properties. To fulfill this purpose, a finite element model has been developed for vibration analysis of a sandwich plate (elastic orthotropic)/(viscoelastic orthotropic)/(elastic orthotropic). A numerical study from the variation of the damping properties of the structures was performed according to the faces materials fibers orientation.
