I+II mixed-mode fatigue crack propagation under combination of tensile loading and corrosion in a HSS specimen

Original language description

Engineering components are often subjected to various unfavourable working environment. Any contact of a metal structure with water can cause development of corrosion pits in its surface area. Therefore, there is a large demand to investigate how such corrosion defects interact with other ones, such as notches, cracks etc. This is the topic investigated within this paper. A rectangular specimen with an angled crack subjected to remote tensile loading is modelled numerically via finite element method. The main goal is to analyse how the crack propagation is influenced by the presence of a corrosion pit located in the very close vicinity of the sharp edge-crack. In the numerical model various geometry parameters can be easily changed in order to investigate the effect of individual parameters. The analysis is made under conditions of the linear elastic fracture mechanics principles. Because the crack is oriented arbitrarily towards the remote tensile loading, the crack propagates under mixed-mode (I + II) loading conditions. Considering the mixed-mode conditions, the crack can deflect from its original direction and this kinking angle can be estimated via various fracture criteria, such as the maximum tangential stress criterion derived by Erdogan and Sih. The results obtained within the study are discussed in detail and several conclusions are stated.
