This paper is devoted to research the dynamic stress-strain behavior of transtropic massif with a few mine tunnels located not too deep from earth surface. Case of propagation and diffraction of elastic SH-waves is considered. Analytical treatment for definition of stresses and strains in condition of anti-plane deformation arc received. An influence of physical and mechanical properties of surround massif and falling SH-waves to stress-strain behavior of shallow located horizontal mine tunnel is shown. Source

The article examines the effect of a magnetic field on corrosive wear. The thickness of the sample subjected to corrosion under the action of a magnetic field was 0.475 mm; the thickness of the sample without the magnetic field was 0.452 mm. It can be seen that corrosive wear of the reference samples is higher than that of the samples emerged in the corrosive medium under the action of a magnetic field. As a corrosive medium, a 10% hydrochloric acid solution was used. Simultaneously, the reference samples with a thickness of 0.5 mm without a magnetic field were investigated. The thickness of the sample subjected to corrosion under the action of a magnetic field was 0.47 mm; the thickness of the sample without a magnetic field was 0.461 mm. Thus, the presence of a magnetic field facilitates retaining a protective passivation film and decreases corrosive wear in both water and an acidic medium. © Pleiades Publishing, Ltd., 2012. Source
