Interfacial waves between two piezoelectric half-spaces with electro-mechanical imperfect interface

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

“…Shi et al (2014) addressed the coupling between mechanical and electric imperfections in a particulate composite in their latest work. The existence of such couplings has been pointed out by Otero et al (2012Otero et al ( , 2013 recently, but the interfacial imperfection formulation employed by them is still an uncoupled model that is the same as those adopted by Fan et al (2006), Shodja et al (2007) and Sun et al (2011). Otero et al (2012Otero et al ( , 2013 declared that they have considered the couplings of the interfacial imperfections.…”

Otero et al (2012Otero et al ( , 2013 declared that they have considered the couplings of the interfacial imperfections. But in fact they are the couplings in the two half-planes on both sides of the interface, which are brought into the interfacial imperfection formulations just due to the introduction of the auxiliary functions.…”

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

“…In this sense, the GLSM only represents a special case of the imperfect interface in such kind of smart composites. Up till now, the interfacial imperfection couplings have been seldom studied [24,25]. To our knowledge, only Shi et al [26] have dealt with the coupling between mechanical and electric imperfections in the interfaces of a particulate piezoelectric composite in their latest work.…”

“…In these generalized cases, the two above-mentioned assumptions are reformulated as follows: (a) the generalized stress is continuous across the interphase, but the generalized displacement therein is discontinuous and (b) the former is proportional to the jump of the latter. In the past decade, the generalized linear spring model (GLSM) has been widely used in studying various boundary value problems (Ang et al, 2004; Chen et al, 2009; Jin and Fang, 2008; Li and Lee, 2009; Otero et al, 2012, 2013; Wang, 2014; Wang and Pan, 2010; Wang and Sudak, 2007; Yuan et al, 2014; Zhou et al, 2012) of composites with imperfect interphases and also in theoretically predicting the effective properties (Duan and Karihaloo, 2007; Wang et al, 2014; Wurkner et al, 2013; Yanase and Ju, 2012; Yue and Xu, 2013).…”
