Boundary contact problems of statics of the moment (couplestress) theory of elasticity are studied in the case of a unilateral contact of two elastic anisotropic nonhomogeneous media. A problem, in which during deformation the contact zone lies within the boundaries of some domain, and a problem, in which the contact zone can extend, are given a separate treatment. Concrete problems suitable fo...

in this paper, the propagation of the waves in the laminated composite plates which is subjected to low velocity impact is investigated using the finite element method. a rigid metallic projectile with spherical nose is considered and the impact of this projectile with laminated composite is studied in this study. considering a finite element model the governing equations of the problem is disc...

Abstract This paper describes a unique experimental set-up constructed for studies of lubricant behaviour in an operating rolling element bearing including situ quantitative measurements film thickness and around the element-raceway contact. The is based on deep groove ball which outer race made sapphire to allow full optical access zone elements are loaded against it. allows direct imaging fil...

To investigate the process and chemistry of mineral reaction zone formation, we conducted detailed petrographic observations chemical analysis rocks minerals spinel lherzolite xenoliths from basanites Tumusun volcano (Baikal Rift Zone). The zones gradually disappear contact toward center xenoliths. influence basanite melt on major trace element composition secondary is notable only at a distanc...

The use of the temperature criterion in design metal-cutting machines, determined on basis models that take into account contact thermal resistances, is an objective necessity. These should to maximum extent actual conditions parts under consideration, by deviations mating surfaces from ideal shape. article presents results numerical modeling based finite element method formation resistance and...
