Determination of bond strength between the hard-faced (HF) layer and the base material (BM) of forging dies
(Faculty of Metallurgy, 2016)
This paper points out complex working conditions of forging dies, which are the most frequent causes of their damage, and proposes suitable hard-facing repair procedures. The shear strength between the hard-faced layer and ...
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 ...

(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2018)
Methods of diagnosing aerodynamic characteristics are constantly developing in order to conduct the precise and energy efficient wind tunnel testing of transport vehicles in the prototype design early stages. This is of a ...
Techno-economic evaluation of residue exhaustion in batch rectification ethanol production plant
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2017)
This paper presents the techno-economic optimization of batch plant for production of rectified alcohol based on the concentration of ethanol in residue. The aim of the analysis was to determine the extent to which it is ...
Selection of the optimal hard facing (HF) technology of damaged forging dies based on cooling time t8/5
(Faculty of Metallurgy, 2016)
In exploitation, the forging dies are exposed to heating up to very high temperatures, variable loads: compressive, impact and shear. In this paper, the reparatory hard facing of the damaged forging dies is considered. The ...
Determining the crack acceptability in the welded joints of a wind loaded cylindrical steel shell structure
(Pergamon-Elsevier Science Ltd, Oxford, 2018)
Engineering critical assessment can be considered as a mandatory request in the civil engineering designing and manufacturing process. The paper is presenting the procedure for determination of crack acceptability based ...
Fracture analysis of the pulley of a bucket wheel boom hoist system
(Polish Maintenance Soc, Lublin, 2016)
This paper presents the results of the pulley fracture analysis. Experimental investigations confirmed that the chemical composition and basic mechanical properties of the pulley material, except the impact energy at a ...
Best Practices of Biomass Energy Life Cycle Assessment and Possible Applications in Serbia
(Zagreb Univ, Fac Forestry, Zagreb, 2016)
This paper aims to highlight the advantages of using Life Cycle Assessment (or LCA) tool in energy sector for rational energy consumption, selection of green technologies and process optimization. Besides the definition ...
3D Digital Image Correlation Analysis of the Shrinkage Strain in Four Dual Cure Composite Cements
(Hindawi Ltd, London, 2019)
