Utilization of Construction and Demolition Mix Waste in the Fired Brick Production: The Impact on Mechanical Properties
(MDPI, 2023)
The European Green Deal, which emphasizes zero-waste economies, and waste recycling
in construction and building materials, has arisen due to significant worldwide needs for solid waste recovery and usage. This ambitious ...
Economical and ecological aspects of use of bio-lubricants and conventional lubricants
(Goriva i maziva, 55, 3, 2016)
It is believed that more than 50% of produced lubricants during or/and after the operation is due directly or indirectly to the environment. For these reasons, in areas where the application of lubricant is related to the ...
Uticaj geometrije trna alata na mehaničke i strukturne karakteristike sučeonog spoja aluminijumske legure 2024-T351 zavarenog postupkom FSW / Influence of pin geometry on mechanical and structural properties of butt friction stir welded 2024-T351 aluminum alloy
(Savez hemijskih inženjera, Beograd, 2015)
U radu je ispitivano kakav zajednički, kombinovani uticaj brzina rotacije alata, brzina zavarivanja i mala promena u geometriji trna alata imaju na zavarljivost, mehaničke i strukturne karakteristike sučeonog spoja Al ...
Uticaj prsline na karakteristike zavarenog spoja pri različitim vrstama opterećenja / Influence of crack on welded joint characteristics in different types of loads
(Vojnotehnički institut, Beograd, 2018)
Primena čelika visoke čvrstoće kod projektovanja zavarenih konstrukcija zahteva podatke o svojstvima istih pri različitim uslovima opterećenja. Zahvaljujući visokom naponu tečenja debljina zida može se smanjiti u poređenju ...
Effect of welded joint imperfection on the integrity of pipe elbows subjected to internal pressure
(Faculty of Mechanical Engineering in Slavonski Brod, Faculty of Electrical Engineering in Osijek, Faculty of Civil Engineering in Osijek, 2013)
Since local defects reduce the load-carrying capacity and deformation ability of a piping system, an analysis is undertaken to quantify the influence of weld defects on integrity of the pipe elbows subjected to internal ...
Analiza trenutnog stanja i ocena čvrstoće cevovoda na hidroelektrani Pirot / Analysis of current state and strength evaluation of the pipeline at hydro power plant 'Pirot'
(DUZS - Društvo za unapređivanje zavarivanja u Srbiji, Beograd, 2018)
Hidroelektrana Pirot, koja je izgrađena 1990 godine, je akumulaciona elektrana derivacionog tipa, koja se sastoji od dva nadzemna vertikalna agregata sa Francis turbinama nominalne snage 41,5 MW, proizvedene u Češkoj ...
Vulkaniti Stolova kao građevinski kamen / Volcanic rocks of Mt. Stolovi as a building stone
(Savez inženjera i tehničara Srbije, Beograd, 2013)
Vulkaniti Stolova južno od Kraljeva predstavljeni su malim vulkanitskim telima dacito-andezita. Ovi vulkaniti su od otvaranja kamenoloma Kamenica pored reke Ribnice korišćeni za dobijanje kocke, agregata i ploča za oblaganje. ...
