Publikováno v: Bulletin of the National Technical University «KhPI» Series: Engineering and CAD. :23-32

In many constructions, their elements are in contact with nominally matching (congruent) surfaces. In reality, this contact is disturbed due to deviations in the shape of these surfaces from the nominal. To study the effect of this perturbation on th
