CONSTRUCTING A MODEL OF THE INTERACTION OF CRACKS IN GAS PIPELINES
DOI: 10.17804/2410-9908.2018.6.255-261 The article presents the results of studying a template with stress corrosion cracking defects. After magnetic particle inspection, a visual analysis of the revealed cracks is carried out in order to fix the traces of mutual influence, which lead to their merging into a common defect with further development. The research has revealed typical ways of crack coalescence, as well as some of their features, and this has allowed us to propose a model for constructing a plausible picture of crack interaction.
