Rad analizira ekonomsku opravdanost i upotrebu nove generacije kabina krana znatno manje težine i krutosti čiji će unutrašnji prostor neophodan za rukovaoca biti razvijen korišćenjem metode fizičkog, kognitivnog i ergonomskog ...
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 ...
