Аннотация доклада:
A two-level contact problem is proposed to study the effect of roughness of elastic coatings. The solution is based on using a function of additional displacements in a macro-level contact problem formulation. The dependence of additional displacements on nominal pressure is obtained from consideration of a periodic model of roughness. Analytical-numerical method, which is based on Hankel integral transforms, boundary elements, and iteration procedure, is used to find macro-contact characteristics. The influence of the parameters of micro-geometry on contact characteristics at macro-scale is analyzed.
