Physical regularities in the cracking of nanocoatings and a method for an automated determination of the crack-network parameters

Abstract

The regularities and spatial distribution of multiple cracking of a nanocoating are investigated. It is found that in the cracking zones the relaxation of the stresses accumulated in the coating takes place; moreover, the intensity of its failure is determined by the structural level of defect accumulation. A new algorithm for a digital identification of the elements of a crack network in a nanocoating is proposed, and its adequacy is checked.

Raziskovali smo zakonitosti in prostorsko porazdelitev vec razpok na nanoprevleki. Ugotovili smo, da pride na podrocjih z razpokami do relaksacije napetosti, nakopicene v prevleki. Intenzivnost njenega propadanja je dolocena s strukturnim nivojem nakopicenja defektov. Predstavljen je nov algoritem za digitalno identifikacijo elementov mreze razpok na nanoprevleki. Preverili smo ustreznost modela.
