“…The simulation method can answer the deficiency of the measured method and is a good way to study the magnetic field distribution of a small or tiny space [2]. After nearly 40 years of development, the computer can be used as a numerical method to solve the problem of the electromagnetic field [17][18][19][20][21]. In the early 1970s, the Finite Element Method (FEM) was referenced in the design of the electromagnetic field by Silvester and Chari [22].…”

“…Since the defects may exist or appear with external loads during the service life and result in destroying the structures, the analysis of structural strength becomes important for the design of magneto-electro-elastic systems. Then as one of the most important fields for the strength analysis, fracture characteristics of magneto-electro-elastic materials have become a topic with increasing interests [5][6][7][8][9].…”

In this work, the interaction between a moving anti-plane crack and a screw dislocation in the magneto-electro-elastic material is studied. The exact solutions are derived by the Muskhelishvili theory and the mechanical-electric-magnetic fields are presented. Comparing with the recent researching status, the present work has three prominent features. Firstly, both the remote loads with eight possible combinations and the coupling of the mechanical-electric-magnetic fields are considered. Secondly, the crack face is assumed to have the general boundary condition which is not the single permeable or impermeable case. Finally, the general solution is derived with the consideration of the crack moving velocity and the screw dislocation. Results presented in this paper would have potential applications on the analysis and design of magneto-electro-elastic structures, especially for the influence of microdefects on the initiation and propagation of cracks.

“…Nevertheless, the main difficulty lies in the fundamental discrepancy between theoretical prediction and experimental observation on the conventional (insulating, unelectroded) crack behavior in piezoelectric materials, as reviewed by Zhang et al (2002), Chen and Lu (2003) and Zhang and Gao (2004). Numerous attempts at reconciling theoretical models with experimental data have been made (e.g., Park and Sun, 1995a,b;Zhang and Tong, 1996;Gao et al, 1997;Fulton and Gao, 2001;McMeeking, 2001McMeeking, , 2004Li, 2003;Gao et al, 2004;Zhang et al, 2005;Haug and McMeeking, 2006;Gao et al, 2008;Zhao and Fan, 2008;Li et al, 2008). Chen (2009a) recently proposed a new formation of the energy flux integral and the energy-momentum tensor for studying the crack driving force in electro-elastodynamic fracture and showed that the dynamic energy release rate thus obtained has an odd dependence on the electric displacement intensity factor, which is in agreement with experimental evidence.…”

a b s t r a c tThe transient response of a Mode-III crack propagating in a magneto-electro-elastic solid subjected to mixed loads is investigated through solving the corresponding boundary-initial-value problem in both the cracked solid region and the interior fluid region with treatment of electro-magnetically permeable and impermeable crack face conditions in a unified way. The closed-form results for the dynamic field intensity factors are used to evaluate the dynamic energy release rate through the crack-tip dynamic contour integral. The permeability of the interior fluid region relative to the cracked solid region significantly affects the magneto-electro-mechanical coupling coefficient in the Bleustein-Gulyaev wave function and, consequently, the horizontal shear surface wave speed, the dynamic field intensity factors and the dynamic energy release rate. It is revealed from dynamic fracture mechanics analysis that the dynamic energy release rate thus obtained has an odd dependence on the dynamic electric displacement intensity factor and the dynamic magnetic induction intensity factor. It is also found that the horizontal shear surface wave speed provides the limiting velocity for the propagation of a Mode-III crack in a magneto-electro-elastic solid when there is only applied traction loading.
