Propagation of slip pulse along frictionless contact interface with local separation between two piezoelectric solids

The Stroh formalism of piezoelectric materials, Fourier analysis and singular integral equation technique were used to investigate the existence of a pulse at the frictionless interface in presence of local separation between two contact piezoelectric solids. The two solids were combined together by uniaxial tractions and laid in the electric field. The problem was cast into a set of Cauchy singular integral equations, from which the closed-form solutions were derived. The numerical discussion on the existence of such a slip pulse was presented. The results show that such a slip pulse, which has square root singularities at both ends of the local separation zone, can propagate in most material combinations. And the existence of such a slip pulse will not be affected by the applied mechanical and electric fields in some special material combinations.

This is a review of research results on conditions under which spatially restricted low-temperature antiferromagnets and their composites can be considered as a special class of acoustic magnetic metamaterials (magnetoacoustic metamaterials). In these, the dynamic magnetoacoustic interaction produces a number of effects that are acoustic analogs of polariton effects and which are currently intensively studied in nonmagnetic acoustic metamaterials. It is shown that the elas-tostatic approach to the analysis of the magnetoelastic dynamics of spatially restricted compensated magnetics is an effective tool in the search for new types of resonance acoustic anomalies, part of which are typical of the magnetostatic spin wave physics (elastostatic bulk and surface spin waves, nonuniform spin±spin resonances with their participation, etc.).Yu V Gulyaev, V G Shavrov V A Kotel'Spin wave acoustics of antiferromagnetic structures as magnetoacoustic metamaterials 576Yu V Gulyaev, S V Tarasenko, V G Shavrov Physics ± Uspekhi 54 (6) June 2011 Spin wave acoustics of antiferromagnetic structures as magnetoacoustic metamaterials 579 Yu V Gulyaev, S V Tarasenko, V G Shavrov Physics ± Uspekhi 54 (6)
