Analysis of current state and integrity evaluation for the supply tank of generation unit 6 of thermal power plant Nikola Tesla ”A”, Obrenovac
(Trans Tech Publications Ltd, 2014)
Stable supply tank, with volume V = 250 m3 and operating pressure p = 1,5 MPa, of generation unit 6 at thermal power plant 'Nikola Tesla A' in Obrenovac, is designed for water-steam working fluid. It was made of steel Č ...
Investigation of the Repair Welding Technology Using Ni Base Electrode
(Trans Tech Publications Ltd, Durnten-Zurich, 2013)
Metal materials are subjected to innumerable time-dependent degradation mechanisms when operate in power, petrochemical and refinery plant. These materials are subjected to multiaxial stresses, creep, fatigue, corrosion ...
Methodology for reparation of damaged sleeves and welded shield sections of guide vanes at hydropower plant DJERDAP 1
(Trans Tech Publications Ltd, 2014)
Vertical Kaplan turbines, manufactured in Russia and with nominal power of 200 MW, have been installed in 6 hydroelectric generating units at ’Djerdap 1’. During the refurbishment of hydropower plant experimental non-destructive ...
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 ...
The influence of corrosion on stress concentration factor at shaft to flange radius
(Springer Netherlands, 2013)
This paper describes the influence of corrosion on stress concentration factor and crack initiation at shaft-flange transition section. The real turbine shaft failure case study is used for research. This case study and ...
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 ...
Effect of changes in matric suction on slope stability in natural unsaturated soil
(ICE Publishing, 2015)
Stability analyses were performed for a real engineering-geological cross-section of unsaturated Quaternary silt sediments. Unsaturated shear strength is a function of the two stress variables: net normal stress and matric ...
Determination of apparent porosity level of refractory concrete using ultrasonic pulse velocity technique and image analysis
(American Ceramic Society, 2011)
Aim of this paper is to establish the correlation between sintering process, porosity and important thermo-mechanical property of refractory concrete, i.e. creep. Creep deformation was investigated according to standard ...
The failures of a supporting structure of a coal-reloading bridge and methodological approach to recovery of the damages
(Univ Novi Sad, Fac Tech Sci, Adeko, Novi Sad, 2012)
In present paper, methodological approach to the analysis of the failures and recovery of the damages has been presented on an example of fracture and damage of a structure of the reloading bridge. The approach presented ...
Determination of the optimal drying condition during drying of green masonry products
(ModTech Publishing House, 2012)
Explanation of the drying process is reduced to the establishment of a series theoretical and empirical drying models. Complex processes of simultaneous mass and energy transfer, which are often non-stationary and the ...
