| Abstract |
A periodic contact problem for a system of indenters and a two-layer elastic half-space is
considered. An algorithm for solving the problem is developed, and a study is carried out of the influence of the geometric and mechanical parameters of the problem, especially the density of indenters,
on the solution of the contact problem and the stress distribution in the layer and half-space. It is
shown that the multiple nature of loading has a particularly significant effect on stresses in relatively
rigid thin coatings. A formulation and method for solving a two-level contact problem that models the
contact of a body with a coating and a rough counter-body is proposed. The method is based on the
use of the additional displacement function obtained by solving the periodic contact problem when
formulating the contact problem at the macro level. It is shown that microgeometry affects the distribution of nominal contact pressure at the macro level. For the contact of a rough coating and a smooth
indenter, an approximate method for solving the contact problem is proposed, which is used to obtain
macro-characteristics of contact interaction. |
