Shear horizontal (SH) waves propagating in piezoelectric–piezomagnetic bilayer system with an imperfect interface

A new interfacial imperfection coupling model (IICM) and its effect on the facture behavior of a layered multiferroic composite: Anti-plane case

“…(1)e(4) to formulate its imperfection is still acceptable to some extent. Due to this reason, the spring model is now so widely used in modeling the imperfect interfaces in various circumstances, from mechanics to multi-physics (Fan and Sze, 2001;Nairn, 2004;Jin and Fang, 2008;Huang et al, 2009;Zhou et al, 2010;Gu and He, 2011;Le Quang et al, 2011;Nie et al, 2012;Rizzoni and Lebon, 2013;Wang and Zhao, 2013;Yuan et al, 2014).…”

Coupled interfacial imperfections and their effects on the fracture behavior of a layered multiferroic cylinder

“…Under harsh conditions, the interfaces in these smart composites may be damaged mechanically, electrically and/or magnetically. Therefore, there has been a new upsurge recently in studying the imperfect interfaces in piezoelectric and/or piezomagnetic composites [9][10][11][12][13]. Generally, the traditional LSMs are simply generalized to formulate the mechanical, electric and/or magnetic imperfections on the interfaces.…”

Effective properties of magnetoelectroelastic interfaces weakened by micro‐cracks

“…The macro‐model in has been widely used for analyzing imperfect interfaces between piezomagnetic/piezoelectric materials (see, for example, Fan et al., Huang and Li, Kuo, Melkumyan and Mai, Nie et al., and Sun et al …”

“…Note that an interface defined by (1) is damaged mechanically, electrically and magnetically, that is, the elastic displacement, the electric potential, and the magnetic potential are all discontinuous across the interface. The macro-model in (1) has been widely used for analyzing imperfect interfaces between piezomagnetic/piezoelectric materials (see, for example, Fan et al, [13] Huang and Li, [15] Kuo, [17] Melkumyan and Mai, [20] Nie et al, [22] and Sun et al [27] ). Most papers in the literature assumed that the jumps in the elastic displacement, the electric potential and the magnetic potential across the interface were decoupled from one another in (1), that is, they assumed that , , , , , and in (1) are null quantities.…”
