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 ...
Gamma and X radiation attenuation characteristics for ultrahigh properties of concrete, concrete with barite and concrete with magnetite and steel
(Niš : RAD Centre, 2023)
During the implementation of construction barrier design procedures for protection against gamma and X radiation, the inevitable question arises of choosing building materials with suitable mechanical and radiation ...
Stabilization of loess with fly ash
(5th Symposium of the Macedonian Association for Geotechnics MAG and 2nd Conference of Regional Geotechnical Societies ISRM Specialized Conference-Engineering problems in soft Rocks, Ohrid; Macedonia, 2022)
To date, much research has been conducted in the field of the application of fly ash in road construction. Particular attention is paid to the effects of fly ash on soil stabilization. The results of the research show that ...
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. ...
Finite element model for stress state analysis of deep groove ball bearings with defects
(Proceedings of the 5th International Scientific Conference, ”Conference on Mechanical Engineering Technologies and Applications” COMETa2020, East Sarajevo, 2020)
In the framework of Industry 4.0, new specific or improved methods for
monitoring and prediction of operational conditions of machine elements are required.
Ball bearings are among the elements with high impact on safety ...
Experimental determination and numerical validation of the critical value of the J-integral ofa low carbon microalloyed steel for elevated temperature application
(VIII INTERNATIONAL CONGRESS ENGINEERING, ENVIRONMENT AND MATERIALS IN PROCESS INDUSTRY EEM 2023, 2023)
To evaluate the behavior of a homogeneous material in the presence of a crack-type defect, the
value of the critical stress-intensity factor, KIc, was determined as a measure of the fracture
toughness of the tested steel ...
