Concentrated force-induced fracture of a multiferroic composite cylinder
Although the cracking problems of multiferroic structures have been widely investigated, concentrated force-induced fracture still remains as an un-fully explored failure mode that has considerable significanc...

Effects of the volume fraction of piezoelectric particles in the magneto-electro-elastic interfacial region on the fracture behavior of a laminate multiferroic plate
Magneto-electro-elastic (MEE) interfacial regions may be formed in multiferroic composites consisting of alternate piezoelectric (PE) and piezomagnetic layers during the hot-pressing process. The existence of ...

Multiple parallel cracks in a magnetoelectroelastic strip under in-plane magnetic/electric field and clam**-induced antiplane pre-deformation
Many magnetoelectroelastic devices are mechanically clamped during service, and the clam** may lead to pre-deformation, which will in return affect the magnetoelectroelastic behavior. In the present paper, a...

Coupled interfacial imperfections and their effects on the fracture behavior of a layered multiferroic cylinder
An interfacial imperfection coupling model is proposed to characterize the imperfect interface in a bi-layered multiferroic cylinder by extending the generalized linear spring model of the uncoupled imperfect ...

Multiple cracks on the interface between a piezoelectric layer and an orthotropic substrate
In the present work, we investigate the problem of multiple cracks on the interface between a piezoelectric layer and an orthotropic substrate. The method of dislocation simulation and singular integral equati...
