Frictionless Contact

AbstractThis paper is concerned with an axially symmetric frictionless contact between an elastically transversely isptropic functionally graded half-space and a rigid base that has a small axisymmetric surface recess. The graded half-space is modeled as a nonhomogeneous medium. We reduce the problem to solving Fredholm integral equations, solve these equations numerically and establish a relationship between the applied pressure and gap radius. The effects of anisotropy and nonhomogeneity parameter of the graded half-space on the normal pressure as well as on the critical pressure have been shown graphically.

The Way

In work researches of phosphate coatings are conducted. By means of methods of mathematical modeling of contact interaction it is established that on wear of phosphate coatings the greatest influence renders their roughness. For decrease in wear of the running-in coverings applied to protection of steel products, the way on increase in service life of phosphate coatings is offered.
