“…The strain, electric, and magnetic fields are related to the elastic displacement, ui, electric potential, Φe, and the magnetic potential, Φm, by the following kinematic relations 17 where the subscript comma denotes the partial differentiation. The thermo-magneto-electro-elastic effect is governed by coupled mechanical equilibrium and magnetic and electric fluxes conservation relations.…”

In the present study, the effect of PZT-5A piezoelectric interphase on the effective thermo-magneto-electro-elastic properties of CoFe2O4 piezomagnetic matrix composites reinforced with carbon fibers is investigated. In this type of three-phase smart composite, the unidirectional fiber is coated with the piezoelectric shell. To this end, the fully coupled thermo-magneto-electro-elastic constitutive relations are developed for a unit cell-based micromechanical model in conjunction with a proper representative volume element. The influences of piezoelectric interphase thickness on the effective properties of the unidirectional smart composite are extensively investigated at different carbon fiber volume fractions up to 70%. The results demonstrate that piezoelectric interphase can greatly affect the overall thermo-magneto-electro-elastic properties of the smart composites. For two-phase smart composites, the present predictions are found to be in close proximity with the Mori–Tanaka results, which validates the present model.

“…The MEE materials with different volume fractions of BaTiO 3 and CoFe 2 O 4 are termed as multiphase magneto-electro-elastic (MMEE) materials (Liu, 2011). The effective material properties, and hence the degree of coupling exhibited by MMEE materials, is directly influenced by the topological textures and volume fractions of BaTiO 3 and CoFe 2 O 4 (Aboudi, 2001; Koutsawa, 2015; Vinyas et al, 2018a; Vinyas and Kattimani, 2018b). MEE materials facilitate energy conversion from one form to the other.…”

The linear frequency response of skew multiphase magneto-electro-elastic composite plate embedded with active constrained layer damping treatment has been studied. The volume fraction of piezoelectric fibres embedded in the piezomagnetic matrix significantly affects the coupling characteristic of this multiferroic material, and hence, the frequency of the skew multiphase magneto-electro-elastic plate is drastically altered. This study emphasizes on evaluating the influence of different volume fraction of barium titanate (BaTiO3) and cobalt ferrite (CoFe2O4) on the frequency characteristics of skew multiphase magneto-electro-elastic. In this regard, a finite element formulation has been proposed to assess the damped response of such skew multiphase magneto-electro-elastic plates. Incorporating the complex modulus approach, the constrained viscoelastic layer of the active constrained layer damping patch is modelled. In addition, the effect of geometrical skewness has also been investigated. Meanwhile, an exhaustive parametric study is carried out to analyse the influence of control gain, patch position and fibre orientation angle of piezoelectric composite.

“…Within the last 30 years, significant progress has been made in the development of models that study the combined thermo-electro-magneto-elastic behaviour of composites (Tang and Yu, 2009;Bravo-Castillero et al, 2009;Akbarzadeh and Chen, 2014;Koutsawa, 2015). Most of the existing models in literature were focused on the thermoelastic regime and have paid particular attention to the study of both piezoelectric and piezomagnetic coupling effects.…”
