Numerical evaluation of thermal stresses generated in laminated composite structure exposed to low temperatures
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2021)
This paper presents numerical calculation of thermal stresses generated in a carbon fiber-epoxy laminated composite structure which is operating at low temperatures. The thermal stress evaluation is based on the finite ...
Mišljenje učenika srednjih škola u Srbiji o prednostima onlajn učenja tokom pandemije Covid-19 / Mnenie učenikov srednih škol v serbii o preimuŝestvah onlajn-obučeniâ vo vremâ pandemii Covid-19
(Pedagoško društvo Srbije, Beograd i Univerzitet u Beogradu - Filozofski fakultet - Institut za pedagogiju i andragogiju, Beograd, 2020)
Poslednjih godina svedoci smo brojnih istraživanja i pilot-projekata, kako kod nas tako i u svetu, koji se bave ispitivanjem onlajn učenja. U radu se teorijski i empirijski analiziraju mogućnosti onlajn učenja. Teorijski ...
Numerical and Experimental Investigations of Fracture Behaviour of Welded Joints with Multiple Defects
(MDPI, Basel, 2021)
Current standards related to welded joint defects (EN ISO 5817) only consider individual cases (i.e., single defect in a welded joint). The question remains about the behaviour of a welded joint in the simultaneous presence ...
Stress Analysis of a Pipeline as a Hydropower Plant Structural Element
(Assoc Mechanical Engineers Technicians Slovenia, Ljubljana, 2020)
This paper describes pipeline stress analysis, primarilybranch junctions, as a structural element in hydro-power plants. Pipelines are exposed to internal pressure,which is present under working conditions. Analysis of ...
Integration of solar energy by nature-inspired optimization in the context of circular economy
(Pergamon-Elsevier Science Ltd, Oxford, 2021)
The purpose of this paper is to make a research on solar power plants integration in an electric power system, taking into account all costs arising from circular economy criteria. Four scenarios of solar power plant ...
Faktori sigurnosti u proračunu debljine zida kolona za rektifikaciju / Safety factors in wall thickness calculation of rectification columns
(Vojnotehnički institut, Beograd, 2021)
Kolone za rektifikaciju gasa veoma su važan deo svake fabrike. Njihovi iznenadni otkazi svakodnevno uzrokuju ogromne gubitke, dok curenje tečnosti može biti veoma opasno po ljude i životnu sredinu. Iz tog razloga, pravilan ...
Fatigue crack growth in a structure exposed to high temperature
(Pergamon-Elsevier Science Ltd, Oxford, 2021)
The exhaust nozzle, made of titanium, is the part of a jet engine where the final expansion of the hot gas from the turbine occurs and where the speed of the exhaust gas is further increased to create thrust. During the ...
Explosive boiling of water films based on molecular dynamics simulations: Effects of film thickness and substrate temperature
(Elsevier, 2023)
This paper deals with investigations of mechanisms governing explosive boiling of water films on hot copper substrate with plain surface. The investigations are based on results of molecular dynamics (MD) simulations in ...
Sistem za rano upozoravanje na poplave zasnovan na internetu stvari / IoT based early warning system for torrential floods
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2020)
S obzirom na to da je pretežno planinska zemlja, u Bosni i Hercegovini se povremeno dešavaju elementarne nepogode, pre svega poplave, koje mogu prouzrokovati značajnu materijalnu štetu i ljudske žrtve. Postojeći sistem za ...
Risk assessment of oil drilling rig welded pipe based on structural integrity and life estimation
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
Risk assessment procedure based on structural integrity and life estimation has been introduced and applied to oil drilling rig welded pipe. The new concept based on application of structural integrity and life estimation ...
