Automated diagnostics of damage to an aluminum alloy under the conditions of high-cycle fatigueMaruščak, P. O. (Avtor) Konovalenko, Igor (Avtor) Karuskevich, Mykhailo (Avtor) Gliha, Vladimir (Avtor) Vuherer, Tomaž (Avtor) fatiguesurfacedigital imagediagnosticsaccumulated damagedefect propagationevaluationAn identification and quantitative analysis of the deformation relief of the aluminium alloy for an aircraft construction based on a digital-image processing has been performed. The behaviour of defects has been assessed on the basis of diagnostics results for individual stages of the deformation process. It has been established that the individual stages of the damage-accumulation process are characterised by the values of integral-image parameters. Based on the consecutive processing of the data on the surface cyclic deformation, the main regularities of the propagation of defects have been found. Theoretical preconditions have been substantiated and experimental results obtained.20132015-07-10 12:39:55Znanstveno delo50438ISSN: 1580-2949UDK: 620.178.3:669.715OceCobissID: 106193664COBISS_ID: 16994070ISSN pri članku: 1580-2949NUK URN: URN:SI:UM:DK:00T0CJQWsl
