Diabase from Drača open pit mine in central Serbia - Quality assessment for building stone purposes
(IOP Publishing Ltd, Bristol, 2021)
Vast masses of basic rocks are present as tectonic blocks and slices along the Eastern deep fault of the Vardar zone of Serbia. They are predominantly comprised of gabbro, with smaller part made up of diabase, and occurrences ...
Komparativna analiza ispitivanja požarnootpornih vrata prema srpskim standardima
(Departman za građevinarstvo i geodeziju, Fakultet tehničkih nauka, Novi Sad, 2021)
Prilikom zaštite zgrada od požara neophodno je podeliti objekte na požarne sektore.
Kako ne bi došlo do prenosa vatre iz jednog požarnog sektora u drugi, potrebno je ugraditi
požarnootporna vrata. Sva ugrađena požarnootporna ...
Determination of ventilation heat losses through building envelope – a case study
(University of Banja Luka Faculty of Architecture, Civil Engineering and Geodesy, 2022)
In this paper the experimental procedure for the determination of ventilation heat losses across building envelopes has been shown. The alternative name for this method is Blower Door Test or Fan Pressurization method. ...
Experimental and numerical analysis of a walls made from aerated concrete blocks exposed to fire
(Proceedings of the 19th International Symposium MASE, Ohrid, 2022, 2022)
The unsteady heat conduction in composite planar structure, with arbitrary number of layers, using analytical approach based on Greeds Functions (GF) is analyzed. The analytical solution for spatial and temporal temperature ...
The role of drainage systems in the prevention of material degradation of bridge structures
(XXIII YuCorr, Divčibare, Serbia, 2022)
The paper gives an illustrative presentation of damage to the material of bridge structures
due to failure to maintain the system for drainage of bridges. Damage is caused by mechanical
erosion and abrasion or by chemical ...
Examination of the physical-chemical and mechanical properties of helical cylindrical compression springs preserved in the Legacy in the Nikola Tesla Museum
(University of Belgrade - Faculty of Mechanical Engineering, Belgrade, Serbia, 2022)
The results of the scientific research work and creativity of Nikola Tesla (Smiljan, 1856 - New York, 1943), a Serbian-American scientist, engineer and inventor, represent the foundation of new technical and technological ...
Analysis of contact fatigue coupled with geometry and material nonlinearities by Theory of critical distances
(2nd Conference on Nonlinearity, Belgrade, 2022)
The contact fatigue is a localized phenomenon that occurs in highly
stressed local zone of the material under the loaded contact region and as such is
highly nonlinear problem. This phenomenon exists in almost all real ...

(International Conference of Experimental and Numerical Investigations and New Technologies CNN TECH 2021, Zlatibor, Serbia, 2021)
The coupling system provides a mechanical connection between European railway vehicles. Screw couplings are designed as a safety device in railway vehicles with coupling links and screw as two main components intended to ...
Neural network model for the condition assessment of hydro turbines
(University of Belgrade - Faculty of Mechanical Engineering, Belgrade, Serbia, 2022)
During regular operation, hydro turbine elements have complex operating conditions. In order to prevent major failures, among other common preventive measures, it is necessary to make a useful model of hydro turbine. ...
Analysis of Hertz contact stresses for metallic material with carbides
(8th International Congress of Serbian Society of Mechanics, Kragujevac, Serbia, 2021)
Hertz contact and the resulting stress-strain state arising from the contact between two elastic solids have practical application in hardness testing, wear and impact damage of engineering ceramics, the design of dental ...
