We have experimentally verified the effect of chessboard-like stress and strain distribution on the surface layer- crystal bulk interface in a deformed solid, which was predicted by A.V. Panin. Under alternating bending of flat titanium VT1-0 specimens with a hydrogenated surface layer, we have obtained a direct experimental verification of the effect of chessboard-like plastic flow distribution at the mesoscale level in the shear-unstable hydrogenated surface layer. All the revealed mesoscopic deformation mechanisms in hydrogenated surface layers of poly- and submicrocrystalline titanium under tension or alternating bending are satisfactorily explained by the shear channeling effect for the chessboard-like structure of the interface 'hydrogenated surface layer - titanium crystal substrate'.
