The Role of the Surface in Crack Initiation in Sharp and Bi-material Notches
Original language description
The study deals with description of stress distribution and conditions of crack initiation in sharp and bi-material notches. Particularly, it uses 3D numerical models of the notches and focuses on stress conditions along the notches fronts, especially near the free surface. The study describes how free surface influences the stress conditions along the notches fronts and whether crack initiates in a central or in a surface layer of the model. It can be shown that some geometries of the notches lead to crack initiation in the central layer, some of them lead to crack initiation in the surface layer, and some notches exhibit stress distribution leading to almost the same probability of crack initiation along whole notch front. The criterion of average tangential stress is used to distinguish the place of failure initiation.
