Dijagnostika stanja i ponašanja čelične konstrukcije rotornih bagera / Structural diagnostics and behaviour of bucket wheel excavator
(Institut za ispitivanje materijala, Beograd, 2010)
Površinski kopovi u Srbiji su osnova proizvodnje uglja, što opravdava usmerenje aktivnosti na neprekidni rad i održavanje mašina i uređaja za površinsku eksploataciju. Složenost konstrukcije rotornih bagera i drugih rudarskih ...
A new methodology for prediction of high-cycle contact fatigue for spur gears
(Univerzitet u Novom Sadu - Fakultet tehničkih nauka, Novi Sad, 2012)
High-cycle contact fatigue is a localized phenomenon that occurs in highly stressed grains of the material on or under the contact region. The contact zones of tooth flanks for meshed gears are subjected to contact fatigue ...
Methodology of determination the influence of corrosion pit on decrease of hydro turbine shaft fatigue life
(Univerzitet u Novom Sadu - Fakultet tehničkih nauka, Novi Sad, 2012)
This paper describes the influence of corrosion on stress concentration factor and crack initiation at shaft flange transition section. The case study of hydraulic turbine shaft failure is used as the basis for this research. ...
An experimental verification of numerical models for the fracture and fatigue of welded structures
(Institute of Metals and Technology, 2007)
By allowing a more detailed analysis, numerical modelling has an important role to play in the development of structures. However, the results of a numerical model's analysis have to be verified with an experimental analysis ...
Analiza rasta prsline u zonama spoja frikciono zavarenog mešanjem korišćenjem proširene metode konačnih elemenata / Crack growth analysis in friction stir welded joint zones using extended finite element method
(Institut za ispitivanje materijala, Beograd, 2013)
U ovom radu je prikazana analiza rasta prsine u zonama zavarenog spoja izvedenog postupkom frikcionog zavarivanja mešanjem (FSW). Ploče od legure aluminijuma 2024-T351 su sučeono zavarene primenom postupka FSW. Ploče su ...
Metodološki pristup proceni integriteta i veka rotacione opreme u hidroelektrani - turbinsko vratilo / Methodological approach to integrity assessment and service life of rotating equipment at hydropower plant: Turbine shaft
(Institut za ispitivanje materijala, Beograd, 2013)
Horizontalne Kaplanove turbine su instalirane u hidroelektrani 'ĐERDAP 2', 10 jedinica ukupne snage 28 MW. Uzimajući u obzir činjenicu da se zamor pojavio u mnogim komponentama, sprovedeno je istraživanje uticaja režima ...
Procena integriteta i veka zavarenih spojeva mikrolegiranih čelika povišene čvrstoće pri dejstvu statičkog i dinamičkog opterećenja / Integrity and life assessment of welded joints made of micro-alloyed high strength steels under static and dynamic loading
(Univerzitet u Beogradu, Mašinski fakultet, 2019)
Integritet zavarenih spojeva predstavlja veoma značajan faktor pri eksploataciji zavarenih konstrukcija, usled njihove heterogenosti i sklonosti ka pojavi i rastu prslina, kao posledica samog postupka zavarivanja. Stoga ...
Damage tolerance analysis of structural components under general load spectrum
(Faculty of Mechanical Engineering in Slavonski Brod, Faculty of Electrical Engineering in Osijek, Faculty of Civil Engineering in Osijek, 2012)
In this investigation fatigue behaviour of damaged structural components under cyclic loads constant amplitude and load spectrum is considered. Primary attention of this investigation is the establishment of computation ...
Corrosion effects on structural integrity and life of oil rig drill pipes
(Savez hemijskih inženjera, Beograd, 2022)
Corrosion effects on structural integrity and life of oil rig welded pipes are analysed by experimental, analytical, and numerical methods. Experiments were performed using standard tensile specimens and CT specimens for ...
Gas cylinder rupture induced by local corrosion damage
(Society for Structural Integrity and Life – Prof. Dr Stojan Sedmak (DIVK), 2018)
Commercial gas cylinders are common type of pressure vessels in many health care and technical facilities. Unexpectedfailures of gas cylinders occur despite of fact that the design, manufacture route, quality control, ...
