Quantification of stress raiser influence on decrease of machine parts fatigue life
(Univ Novi Sad, Fac Tech Sci, Adeko, Novi Sad, 2012)
This paper displays the usage of Theory of Critical Distances (TCD) in the prediction of high-cycle fatigue behaviour in machine parts and systems. It is possible to gain real overview of stresses of machine parts by Finite ...
Prediction of crack initiation in spur gear contact zone
(Univ Novi Sad, Fac Tech Sci, Adeko, Novi Sad, 2012)
The objective of this paper is to give a new viewpoint in contact fatigue prediction in the case of high-cycle fatigue. The presented research is based on up-to-date methods and multidisciplinary approach, and enables ...
Uticaj prsline na karakteristike zavarenog spoja pri različitim vrstama opterećenja / Influence of crack on welded joint characteristics in different types of loads
(Vojnotehnički institut, Beograd, 2018)
Primena čelika visoke čvrstoće kod projektovanja zavarenih konstrukcija zahteva podatke o svojstvima istih pri različitim uslovima opterećenja. Zahvaljujući visokom naponu tečenja debljina zida može se smanjiti u poređenju ...
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. ...
Morphology of corrosion fatigue and stress corrosion cracks on low alloy steels
(Society for Structural Integrity and Life – Prof. Dr Stojan Sedmak (DIVK), 2018)
The fracture surface appearances are slowly changed through decade’s side by advantages in technology of steel production.
Basic requirements for cleaner steels and lower energy consumption during production induce that ...
Comprehensive approach to weld repair on elements of power transmission – case study for hydro turbine shaft
(Proceedings of the The 4th IIW South – East European Welding Congress, October, 10-13, 2018, Belgrade, 2018)
Turbine and generator rotors and shafts undergo high
stresses during regular working life and, from a safety
and operational aspect, are the most significant
components of a power generation system. Depending
on the ...
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. Unexpected
failures of gas cylinders occur despite of fact that the design, manufacture route, quality control, ...
Feasibility Analysis for Repair of Large Diameter Hydro Turbine Shaft Based on Weldability Test and Welding Cycle Simulation
(Advanced Materials Research, 2019)
Turbine and generator rotors and shafts undergo high stresses during regular working life
and, from a safety and operational aspect, are the most significant components of a power
generation system. Depending on the ...
Application of gradient elasticity on corrosion fatigue damage assessment
(Proceedings of the 6th International Congress of Serbian Society of Mechanics, Tara, Serbia, 2017)
Researchers in the field of fracture mechanics, today predominantly developing appropriate
solution algorithms for problems of solid bodies with cracks. Problems in mechanics
generally, related with fracture and fatigue ...
