Prediction and prevention of boiler tubing systems erosion in thermal plant
(Visoka tehnička škola strukovnih studija, Beograd, 2010)
The problem of boiler tube erosion is a very complex problem and present in practically all fossil fuel power plants burning low heating value coals irrespective of their particular design and operating characteristics. ...
Dijagnostika stanja i ponašanja čelične konstrukcije rotornih bagera / Structural diagnostics and behaviour of bucket wheel excavator
(Institut za ispitivanje materijala, Beograd, 2010)
Površinski kopovi u Srbiji su osnova proizvodnje uglja, što opravdava usmerenje aktivnosti na neprekidni rad i održavanje mašina i uređaja za površinsku eksploataciju. Složenost konstrukcije rotornih bagera i drugih rudarskih ...
Tehnologija zavarivanja aluminijumskih legura postupkom zavarivanja trenjem alatom / Welding technology of aluminium alloys using friction stir welding
(DUZS - Društvo za unapređivanje zavarivanja u Srbiji, Beograd, 2010)
Cilj rada je osvajanje tehnologije zavarivanja aluminijumskih legura postupkom zavarivanja trenjem alatom (FSW). Zavarivanje trenjem alatom predstavlja jedan od najsavremenijih postupaka, sa velikom perspektivom dalje ...
Numeričko modelovanje otvaranja vrha prsline u zavarenom spoju / Numerical modeling of crack tip opening in welded joint
(Institut za ispitivanje materijala, Beograd, 2010)
Zavareni spoj je heterogene strukture sa područjima različitih mikrostruktura. Da bi ispitali lokalno ponašanje područja prateći otvaranje prsline, problem je postaviti vrh zareza u željeni položaj. Izvedena je simulacija ...
