Abstract: The adjoint 3-D problem of shock local interaction of a liquid with the nonlinear deformable, damaged medium in the presence of the finite deformations is formulated and solved. Liquid influence is considered a kind of a shock wave or the high-speed jet, formed at collapse of bubbles of cavitation owing to axisymmetric or them cumulative compression at the front an extending shock wave. The special attention is thus given influence of wettability of a deformable surface.

Keywords: cavitation; a two-phase liquid; wettability; damageability of the deformable medium; erosive fatique.
