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. ...
Analysis of contact fatigue coupled with geometry and material nonlinearities by Theory of critical distances
(2nd Conference on Nonlinearity, Belgrade, )
The contact fatigue is a localized phenomenon that occurs in highlystressed local zone of the material under the loaded contact region and as such ishighly nonlinear problem. This phenomenon exists in almost all real ...

Turbine and generator rotors and shafts undergo highstresses during regular working life and, from a safetyand operational aspect, are the most significantcomponents of a power generation system. Dependingon the appropriate ...
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, ...
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 ...
Hronologija gubitka integriteta konstrukcija zbog grešaka izrade zavarenih konstrukcija / Chronology of lost structural integrity initiated from manufacturing defects in welded structures
