The behavior of coated media is investigated using the block element method under
the assumption that the coating is exposed to a liquid substance that gradually leads to the
destruction of the coating. It is assumed that the coating contains many defects that are
parallel to each other. A similar situation occurs when the body is bent around the axis in a
liquid medium, resulting in high tensile stresses in the coating. Such problems occur in
bearing pairs. Another example of such a situation occurs in seismology, in the subduction
zone, which represents the advance of oceanic lithospheric plates under the continental ones.
