Originální abstrakt

The objective of the paper is to investigate the direction of a further crack propagation from the interface between two elastic materials. The angle of crack propagation changes when the crack passes the interface. The suggested procedure based on a generalized form of Sihs strain energy density factor makes it possible to estimate an angle of propagation under which the crack will propagate into the second material. The assumptions of linear elastic fracture mechanics and the elastic behavior of the body with interfaces are considered. The finite element method was used for numerical 2D and 3D calculations. The results obtained might contribute to a better understanding of the failure of materials with interfaces (e.g. layered composites, materials with protective coatings, etc.).
