    Valley Hall edge solitons in honeycomb lattice with an armchair-type domain wall

    Thanks to the topological protection, photonic topological edge states can move along the edges of photonic crystals without radiating into the bulk or reflecting when encountering disorders or defects. The va...

    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...
