“…Comparative results for the first three modal loss factors are presented in Table 2, using a 12 × 12 mesh for both present and reported [22,25] results, where a good agreement can be observed. The approximate nature of the energy method used by Rikards et al [22] to calculate the modal loss factor might explain the deviations observed.…”

“…In this paper we present comparative results for passive damping with the ones reported by Rikards at al. [22], which include experimental data. As for hybrid damping, we compare our solutions with the ones reported by Boudaoud et al [13], which, to the authors' knowledge, are the only ones available in the literature for hybrid active-passive sandwich plates with colocated control.…”

In this paper we present a finite element model for the analysis of active sandwich laminated plates with a viscoelastic core and laminated anisotropic face layers, as well as piezoelectric sensor and actuator layers. The model is formulated using a mixed layerwise approach, by considering a higher order shear deformation theory (HSDT) to represent the displacement field of the viscoelastic core and a first order shear deformation theory (FSDT) for the displacement field of the adjacent laminated anisotropic face layers and exterior piezoelectric layers. The dynamic problem is solved in the frequency domain with viscoelastic frequency dependent material properties for the core. Control laws are also implemented for the piezoelectric sensors and actuators. The model behaviour in dynamics is assessed with the few solutions found in the literature, including experimental data, and a laminated composite active sandwich application is proposed. In this numerical application, velocity feedback control law is implemented for active control, using co-located piezoelectric patch sensors and actuators.

The response of structures made from viscoelastic materials to transient excitations is studied using the finite element method. The viscoelastic material behaviour is represented by the complex modulus model. An efficient method using fast Fourier transform has been developed. This method is based on the trigonometrical representation of the input signals and matrix of the transfer functions. The present implementation gives the possibility to preserve exactly the frequency dependence of the storage and loss moduli of materials. On this reason this time‐domain representation is a mathematically correct way to avoid the non‐causal effect. Test problems and numerical examples are given to demonstrate the validity and effectiveness of the approach suggested in this paper. Copyright © 1999 John Wiley & Sons, Ltd.
