Profili nastavnika osnovnih škola u Srbiji prema opredeljenju za nastavni model tokom pandemije COVID-19 / The Serbian primary school teachers' profiles regarding the preference for a teaching model during the COVID-19 pandemics
(Univerzitet u Novom Sadu - Pedagoški fakultet, Sombor, 2021)
Kvalitet nastavnog procesa u velikoj meri zavisi od nastavnika i njihovih kvalifikacija - uloga nastavnika je veoma značajna za uspešnu implementaciju novih nastavnih metoda. Ovaj rad je deo kvantitativne studije ispitivanja ...
Mogućnost rekonstrukcije saobraćajnih nesreća pomoću uređaja za beleženje podataka - pregledni rad / The possibility of traffic accident reconstruction using event data Recorders: A review
(Ekonomski institut, Beograd, 2021)
Uređaji za beleženje podataka koriste se u svrhu istraga saobraćajnih nesreća više od 20 godina. Neke zemlje su zakonski regulisale njihovu primenu i validan su dokaz u istragama i rekonstrukcijama. Međutim, uređaji za ...
Assessment of integrity of pressure vessels for compressed air
(Institut za ispitivanje materijala, Beograd, 2021)
Fracture mechanics approach for structural integrity assessment is described in the case of pressure vessels for compressed air. The results of non-destructive testing indicated unacceptable defects on the vessels and set ...
Numerical Simulation of Fatigue Crack Growth in Titanium Alloy Orthopaedic Plates
(Univ Osijek, Tech Fac, Slavonski Brod, 2020)
Biomaterials intended for orthopaedic plates manufacturing have much higher mechanical properties relative to the bone itself and still there are many cases where those plates fracture in service, with fatigue as the main ...
Crack initiation and propagation resistance of hsla steel welded joint constituents
(Institut za ispitivanje materijala, Beograd, 2020)
The welded joint is heterogeneous in its microstructure, mechanical and geometrical properties, thus the stress field is affected by different factors as well as by residual stress. Therefore, special procedures are needed ...
The largest pre-stressed concrete Dome in the world - the case study of "Hall 1 of the Belgrade Fair"
(Elsevier, Amsterdam, 2020)
The aim of the paper is to present the largest pre-stressed concrete free-standing structure in the world the Dome of the "Hall 1 of the Belgrade Fair", designed by Academician Branko ZeZelj, prominent Serbian scientist, ...
Design Aspects of Hip Implant Made of Ti-6Al-4V Extra Low Interstitials Alloy
(Elsevier Science Bv, Amsterdam, 2020)
The main concerns in design of hip implants are fracture and fatigue related issues. In this paper, reverse engineering is used to redesign a hip implant produced by precision casting, using Ti6Al4V Extra Low Interstitials ...
Extended FEM analysis of fatigue crack growth in Ti-6Al-4V orthopaedic plates
(Elsevier, Amsterdam, 2020)
The extended finite element method (xFEM) was used to analyse fatigue crack growth in orthopaedic locking compression plates (LCP), made of Titanium alloy, Ti-6Al-4V, loaded in four-point bending. The optimal geometry was ...
Analytical vs Numerical Calculation of Fatigue Life for Different Welded Joint Regions
(Univ Osijek, Tech Fac, Slavonski Brod, 2020)
This research will show the analytical way of determining the remaining life of a welded joint with a fatigue crack initiated in its heat affected zone. The calculation will be divided into two stages, since the fatigue ...
Manufacturing and integrity of ammonia storage tanks
(Institut za ispitivanje materijala, Beograd, 2020)
Manufacturing ammonia storage tanks represents a very demanding and responsible task. The paper presents the methodology for manufacturing two ammonia storage tanks in Russia, along with all the necessary steps. The base ...
