ANALÝZA STABILITY TRHLINY V POVRCHOVÝCH OCHRANNÝCH VSTVÁCH NA ZÁKLADĚ OTEVŘENÍ TRHLINY NA POVRCHU TĚLESA

Original language description

Paper deals with stability analysis of a crack in a coating on a substrate. It is considered that the crack is perpendicularly oriented to the interface between the coating and the substrate and the crack tip lies directly on the material interface. Thesimple method based on crack mouth opening displacement parametr CMOD is proposed here for a critical stress calculation in the case of throught coating crack in very thin coatings. The method is then aplicated herein on the model example and the critical stresses for different material combinations of the coating and the substrate are calculated. Note that under these stresses the crack will start propagace accros the interface to the substrate. All calculations are performed by a finite element methodFEM in the system ANSYS.
