Determining the theoretical reliability function of thermal power system using simple and complex weibull distribution
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
The main subject of this paper is the representation of the probabilistic technique for thermal power system reliability assessment. Exploitation research of the reliability of the fossil fuel power plant system has defined ...
Thermomechanics of soft inelastics bodies with application to asphalt behavior
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
Thermomechanical behavior of hot mix asphalt (HMA) is considered. Its highly irregular microstructure is covered by the hierarchical approach. A brief survey of endochronic thermodynamics precedes constitutive consideration. ...
Influence of friction stir welding parameters on properties of 2024 t3 aluminium alloy joints
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
The aim of this work is to analyse the process of friction stir welding (FSW) of 3 mm thick aluminium plates made of high strength aluminium alloy - 2024 T3, as well as to assess the mechanical properties of the produced ...
Numerical analysis of temperature field during hardfacing process and comparison with experimental results
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
The three-dimensional transient nonlinear thermal analysis of the hard facing process is performed by using the finite element method. The simulations were executed on the open source Salome platform using the open source ...
Water deoxygenation using hollow fiber membrane module with nitrogen as inert gas
(Taylor & Francis Inc, Philadelphia, 2015)
A pilot plant scale fiber membrane system was developed for the removal of dissolved oxygen from water via nitrogen vacuum. Feed water was introduced to the shell side; a nitrogen gas was applied to the lumen side, as an ...
Identification of low cycle fatigue parameters of high strength low-alloy (hsla) steel at room temperature
(Croatian Metallurgical Soc, Zagreb, 2014)
Low cycle fatigue test was performed in ambient atmosphere at room temperature. cycle loading of material, in case of High strength low-alloy steel, entails modifications of its properties and in this paper is therefore ...
Failure investigation and reparation of a crack on the boom of the bucket wheel excavator ERS 1250 Gacko
(Pergamon-Elsevier Science Ltd, Oxford, 2018)
Bucket wheel excavator ERs 1250 has been in operation for over 30 years in the Grae'anica-Gacko mining basin. It is operating in very hard working conditions due to exploiting very solid material, which has adverse effects ...
Effect of aging on mechanical properties of Al-8Si-8Fe-1.4v/SiCp composites
(Faculty of Metallurgy, 2016)
In this study, Al-8Fe-8Si-1.4V/SiCp composites fabricated by squeeze casting process were age-hardened to Study the influence of heat treatment on mechanical properties, such as hardness, bending strength and modulus of ...
