(Institut za ispitivanje materijala, Beograd, 2017)
The results of the research regarding the stress and strain state in structural elements of the container terminal are presented in this paper. The container terminal is used for the electrical energy supply and control ...
Expectations, reality and perspectives in using bim for the green building design
(Institut za ispitivanje materijala, Beograd, 2017)
In the late 1970s when the first programs for building energy consumption simulation appeared, architectural practice was based on paper documentation and 2D drafting programs were considered as state of the art technologies. ...
Cracking due to repair welding of the treiber roll
(Institut za ispitivanje materijala, Beograd, 2017)
Repair welding has caused crack initiation in the upper Treiber roll in the steel works plant mill at Zelezara in Smederevo. The upper and lower Treiber rolls serve the purpose of folding and directing rolled metal strips, ...
Remaining life determination for pressure vessel in a refinery
(Institut za ispitivanje materijala, Beograd, 2016)
Repair and inspection has been performed on a pressure vessel in the oil refinery for downstream treatment of crude oil in Iraq, without technical documentation. Two different approaches have given totally different results ...
Impact of austenitic steels' mechanical properties on allowed stress and wall thickness of pressure equipment
(Institut za ispitivanje materijala, Beograd, 2018)
The Pressure Equipment Directive (PED) and Regulations on Technical Requirements for Designing, Manufacturing and Conformity Assessment of Pressure Equipment bring a number of changes to the design of pressure equipment ...
Određivanje vrednosti unutrašnjeg pritiska koji će dovesti do plastične deformacije na modelu račve / Determination of internal pressure value causing pipe branch model to plastically deform
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2018)
Složenost geometrije posuda pod pritiskom obično predstavlja uzrok pojave koncentracije napona i deformacija. Savremeni pristup analize stanja napona i deformacija uključuje numerička i eksperimentalna ispitivanja. Svako ...

Izvijanje cilindrične tankozide strukture izrađene od legure aluminijuma sa greškom u geometriji u vidu udubljenja, pod dejstvom aksijalnog pritiska / Buckling behaviour of dented aluminium alloy cylindrical shell subjected to uniform axial compression
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2017)
Tankozide cilindrične strukture imaju veoma visoku primenu u industriji. Pošto su obično opterećene na aksijalni pritisak, najčešći uzrok njihovog otkaza je pojava izvijanja. U ovom članku se prikazuje numerička analiza ...
Integrity assessment of vital beam components that enable conjoint operation of two bridge cranes
(Institut za ispitivanje materijala, Beograd, 2018)
Vital components of the beam that enable conjoint operation of two bridge cranes are braces and threaded spindle. The beam connects two bridge cranes with overall lifting capacity of 500 t (2 x 250 t) and enables their ...
Istraživanje geometrijskih karakteristika pravozubih konusnih zupčanika sa malim uglom gornjeg konusa bez ozubljenog većeg a sa ozubljenim manjim zupčanikom / Research on geometrical characteristics of straight bevel gears with a small shaft angle with a non-generated gear and generated pinion
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2017)
Korišćenjem konusnih zupčanika sa malim uglom precesije gornjeg konusa razvijen je pogon za jedan deo opreme na gas i ulje. Zupčanici se odlikuju visokim stepenom iskorišćenosti (oko 0,9) i malim početnim obrtnim momentom. ...
