TL;DR: A linear electro-mechanically coupled finite element (FE) model for composite laminated thin-walled smart structures bonded with orthotropic MFCs having arbitrary piezo fiber orientation was developed in this paper.

TL;DR: In this paper, a general linear theory of laminated composite anisotropic shells of arbitrary shape and curvature is presented, in which the effect of the interfacial damage induced by the imperfect bonding between the constituent laminae is incorporated.

TL;DR: In this paper, an electro-mechanically coupled finite element (FE) model of smart structures is developed based on first-order shear deformation (FOSD) hypothesis, and a PID control is implemented to damp both the free and forced vibrations.

TL;DR: In this article, the relevance of the five and six-parameter variants of the FOSD hypothesis for large rotation plate and shell problems was discussed, and it was shown that the assumption of constant through-thickness distribution of the transverse normal displacements is acceptable only for small and moderate rotation problems.

TL;DR: Hybrid composite pyramidal truss sandwich panels combined with multiple damping configurations are fabricated in this article to investigate the damping and stiffness efficiency of the candidate structures, and experimental results show that such structures combined with damping materials would significantly improve damping loss efficiency but decrease simultaneously the stiffness efficiency in varying degrees compared with the bare hybrid sandwich panels.
