Predviđanje veka čeličnog žičanog užeta u eksploataciji / Service life prediction of running steel wire ropes
(Institut za ispitivanje materijala, Beograd, 2010)
Vrlo visoka čvrstoća omogućava žičanom užetu da prenese velike zatezne sile i da se kreće po koturima relativno malog prečnika. Žice od čelika vrlo visoke čvrstoće su postojale više od sto godina pre nego što su patentirane, ...
Fem model for calculation of hydro turbine shaft
(Univ Novi Sad, Fac Tech Sci, Adeko, Novi Sad, 2010)
This paper describes the real problem calculation of stress state of hydro turbine shaft with crack appearance on shaft-flange radii. Finite element method (FEM) is used for calculation of shaft stress state and shaft ...
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 ...
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 ...
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 ...
Iskorišćavanje otparka u parno-kotlovskom postrojenju u prehrambenoj industriji
(Beograd : Institut za istraživanja i projektovanja u privredi, 2015)
U postrojenjima za proizvodnju tehnološke pare javlja se problem gubitka toplotne energije i hemijski pripremljene vode, jer se otparak koji nastaje pri obaranju pritiska kondenzata ispred rezervoara kondenzata izbacuje u ...
Determination of cavitation resistance of sintered basalt samples
(51st International October Conference on Mining and Metallurgy, 16-19 October 2019, Bor Lake, Proceedings, 2019)
The paper examines the cavitation resistance of the sintered basalt samples. A change in the sample mass in function of the cavitation time was monitored for the evaluation of cavitation resistance. The level of degradation ...

In this paper, results of investigation of casting technology of complex thin-wall copper alloy castings with accent on Lost Foam casting procedure are given. Phases of casting procedure were investigated, along with ...
SUSTAINABLE DEVELOPMENT AND ENVIRONMENTAL QUALITY ENHANCEMENT AS A MOTIVATION FACTOR FOR LAND MANAGEMENT METHOD RESEARCH
(International May Conference on Strategic Management IMKSM2013, 24-26. May 2013, Bor, Serbia, 2013)
Environmental quality increase and global worming prevention are strong motivation
factor for research in the field of land management recovering. Coal, as non renewable
resources and its exploitation causes immense ...
Application of polymer materials for production of evaporative pattern and development of new casting process
(44rd International October Conference on Mining and Metallurgy, October 01–03, 2012, Bor, Serbia, Proceedings, 2012)
In this paper, results of the investigation of the polymer materials for evaporate patterns and their application in the new casting method (EPC process) are presented. The basic characteristic of EPC process is that ...
