Título: | Profile and Areal Surface Parameters for Fatigue Fracture Characterisation | Autor: | Macek, Wojciech Branco, Ricardo Szala, Mirosław Marciniak, Zbigniew Ulewicz, Robert Sczygiol, Norbert Kardasz, Piotr |
Palavras-chave: | surface metrology; surface topography; bending–torsion fatigue; fatigue fracture | Data: | 20-Ago-2020 | Editora: | MDPI | Projeto: | Lublin University of Technology—Regional Excellence Initiative, funded by the Polish Ministry of Science and Higher Education (contract no. 030/RID/2018/19). | Título da revista, periódico, livro ou evento: | Materials | Volume: | 13 | Número: | 17 | Resumo: | Post-mortem characterisation is a pivotal tool to trace back to the origin of structural failures in modern engineering analyses. This work compared both the crack propagation and rupture roughness profiles based on areal parameters for total fracture area. Notched and smooth samples made of weather-resistant structural steel (10HNAP), popular S355J2 structural steel and aluminium alloy AW-2017A under bending, torsion and combined bending-torsion were investigated. After the fatigue tests, fatigue fractures were measured with an optical profilometer, and the relevant surface parameters were critically compared. The results showed a great impact of the loading scenario on both the local profiles and total fracture areas. Both approaches (local and total fracture zones) for specimens with different geometries were investigated. For all specimens, measured texture parameters decreased in the following order: total area, rupture area and propagation area. | URI: | https://hdl.handle.net/10316/106359 | ISSN: | 1996-1944 | DOI: | 10.3390/ma13173691 | Direitos: | openAccess |
