20.500.12556/RUL-136084 Experimental crack path analysis of aluminum alloy specimen under dynamic shear loading using digital image correlation method The present paper investigates crack growth in specially designed specimens of 6061 aluminum alloy sheets subjected to dynamic shear loads. The sheets were previously thoroughly tested using uni-axial static and dynamic tests, so the less-known shear fatigue tests are presented in this work. For this purpose, a special specimen and fixtures were designed, which are capable of fatigue shear testing at elevated temperatures. In addition, the shape of the specimen was designed for more predictable crack initiation and growth along the specimen surface. In this study, the specimens were tested with low frequency (0.2 Hz) alternating shear loading (amplitude 0.3 mm in the positive and negative directions) until complete fracture. Each time the peak amplitude was reached, a photograph of the shear area on the specimen surface was taken and used to investigate crack growth further. The main objective of this work was to observe the crack initialization and crack growth under alternating shear loading using Digital Image Correlation (DIC) method; this was achieved by analyzing the photographs taken with the DIC method by observing local in-plane fields of strains and displacements. crack observation shear fatigue digital image correlation opazovanje razpoke strižno utrujanje materiala metoda digitalne korelacije slik true false true Angleški jezik Slovenski jezik Članek v reviji 2022-04-11 11:38:12 2022-04-11 11:38:18 2023-03-21 09:32:59 0000-00-00 00:00:00 2022 0 0 Str. 41-46 Vol. 39 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 620.191.33 2452-3216 10.1016/j.prostr.2022.03.070 104056067 104053507 RAZ_Litrop_Aljaz_2022.pdf RAZ_Litrop_Aljaz_2022.pdf 1 0EC033F69B5EB52C27F55A2107545D75 caf26a9da0bff007a8e7ffb0e8c4a7dcf4620c3ca103571aeb9e4c98a14e1801 a101f7a3-b97b-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=155538 https://www.sciencedirect.com/science/article/pii/S2452321622002839 1 120f741f-b97b-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=155537 Fakulteta za strojništvo 0 0 0
