20.500.12556/DKUM-50438 Automated diagnostics of damage to an aluminum alloy under the conditions of high-cycle fatigue Avtomatizirana diagnostika poškodbe aluminijeve zlitine pri visoko-cikličnem utrujanju An 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. Identificirali in kvantitativno analizirali smo relief deformirane površine aluminijeve zlitine za gradnjo letal. Temelj obojega je izdelava digitalne podobe površine vzorcev. Oceno vedenja defektov omogočajo rezultati diagnostike posameznih stopenj deformacijskega procesa. Ugotovili smo, da so te stopnje med akumulacijo poškodbe značilne po vrednostih integralnih parametrov slike. Na osnovi zaporedne obdelave podatkov ciklične deformacije na površini smo ugotovili glavne zakonitosti pri širjenju defektov. Tako smo dokazali teoretične predpostavke in pridobili eksperimentalne podatke. fatigue surface digital image diagnostics accumulated damage defect propagation evaluation aluminijeve zlitine utrujanje površina preiskava materiala true false true Angleški jezik Slovenski jezik Znanstveno delo 2015-07-10 12:39:55 2015-07-10 12:39:55 2022-05-29 03:07:00 2021-05-09 03:28:08 2013 0 0 str. 357-361 št. 3 Letn. 47 maj-jun. 2013 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1580-2949 620.178.3:669.715 106193664 16994070 1580-2949 URN:SI:UM:DK:00T0CJQW Materiali_in_Tehnologije_2013_Maruschak_et_al._Automated_Diagnostics_of_Damage_To_an_Aluminum_Alloy_Under_the_Conditions_of_High-Cycle_F.pdf Materiali_in_Tehnologije_2013_Maruschak_et_al._Automated_Diagnostics_of_Damage_To_an_Aluminum_Alloy_Under_the_Conditions_of_High-Cycle_F.pdf 1 C9EEBC9F7D35407BB786FBD89207DD76 a1c5cc424aae05145491f1c0cba67bf4de7c0bfad3de36aa220477c9912980c0 fc0300a9-7c0d-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=109786 http://mit.imt.si/Revija/izvodi/mit133/maruschak.htm 1 https://dk.um.si/Dokument.php?lang=slv&id=74997 Fakulteta za strojništvo 0 0 0
