Název v původním jazyce

Determination of crack propagation direction using approach based on generalized linear elastic fracture

Popis výsledku v původním jazyce

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, due to different material properties of layers. The suggested procedure makes it possible to estimate an angle of crack propagation under which the crack will propagate into the second material. The assumptions of (generalized) linear elastic fracture mechanics, which takes into account stress singularity exponent different from 1/2 are considered. The finite element method was used for numerical calculations. As an example application of the suggested approach on crack propagation through laminar ceramics (residual stresses in individual layers are taken into account) is introduced and results obtained compared with experimental data. The results obtained might contribute to a better understanding of the failure of materials with interfaces (e.g. layered composites, materi
