Abstract

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.

Keywords: cracks, block elements, coatings with defects, Kirchhoff plates, liquid layer, set of defects, stress concentration, subduction, tsunami
