Effects of electromagnetic fields on the contact of magneto-electro-elastic materials

A review of advances in tribology in 2020–2021

“…Çömez [917] solved the 2D frictional sliding contact problem between an MEE half-plane and conducting punches with given total electric and magnetic charges, and investigated the effects of sliding velocity on contact width and stresses. Sui et al [918] solved the 3D frictional contact between a MEE material and a perfectly conducting rigid spherical punch under electromagnetic fields based on the semi-analytical method (SAM), in which the frequency response functions (FRFs) with respect to unit mechanical, electric, and magnetic loads were derived and the surface density (closed circuit) or total amount (open circuit) of electric and magnetic charges were considered. It is found that the change of electric field presents significant effects on the contact behavior comparing with magnetic field, as shown in Fig.…”

Thermal Contact Response of a Transversely Isotropic Magneto-Electro-Elastic Coating

“…Some have also paid attention to the effects of the electromagnetic field on the contact response. Sui et al [ 20 ] established a semi-analytical contact model for a 3D MEE material and found that the electric field can control the magnetic field via strain transfer but not vice versa. Under external loading, stress concentration means that damage to the material unavoidably occurs, becoming a concern for some researchers.…”
