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 ...
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. ...
API J55 Steel Casing Pipe with an Initial Surface Crack under Internal Pressure - Determination of Fracture Parameters
(Trans Tech Publications Ltd, Durnten-Zurich, 2012)
Seam casing pipe used in an oil drilling rig, manufactured by high frequency (HF) contact welding of API J55 steel, is tested. The influence of an initial defect (machined surface crack) is analysed, by performing pressure ...
Energetic and environmental sustainability of sub-geothermal heat pump heating in Serbia
(Journal of Environmental Protection and Ecology, 2012)
Feasibility of low enthalpy geothermal waters incorporation in Serbian energy source structure has been investigated. Energy potential of ground waters of modest temperature levels is usually neglected since they can not ...
Experimental analysis of artificial hip implant made of titanium alloy
(University of Belgrade, 2012)
Computational and experimental investigation into subsonic flow around a finned ogive cylinder
(Transactions of Famena, 2012)
Experimental and numerical investigation into the flow around an ogive cylinder with fins (missile calibration model) was conducted for Mach 0.6 flow. The computational results were compared to the results of pressure-distribution ...
Merenje i analiza vibracija na helikopterskoj strukturi sa ciljem otkrivanja defekta radnih elemenata / Measurement and analysis of vibrations on the helicopter structure in order to detect defects of operating elements
(Vojnotehnički institut, Beograd, 2012)
U radu je prezentovan praktičan primer merenja i analize vibracija na helikopterskoj strukturi sa ciljem da se otkriju potencijalna oštećenja radnih elemenata. Sveobuhvatna metodologija merenja vibracija je predstavljena ...
Compressive strains and displacement in a partially dentate lower jaw rehabilitated with two different treatment modalities
(Wiley, Hoboken, 2012)
Background: Understanding of the biomechanical consequences of the stresses generated to the supporting bone during occlusal loading is significant for improving the design and clinical planning process in partial edentulism ...
Condition and behaviour diagnostics of drive groups on belt conveyors
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
Belt conveyors are complex systems with drive groups as functionally very important components. Their proper and reliable operational life is directly related to durability of the load-bearing steel structures. Drive units ...
