Komparativna nelinearna analiza interakcije šip-tlo AB 2D rama / Comparative nonlinear analysis of a RC 2D frame soil-pile interaction
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2018)
U radu je sprovedena komparativna nelinearna statička (NSA) i nelinearna dinamička analiza (NDA) seizmičkog ponašanja rama kao dela skeletne konstrukcije AB zgrade fundirane na šipovima. Da bi se dobila realnija slika ...
Algoritam za proračun uticaja promene temperature transformatorskog ulja na preciznost lokalizacije parcijalnog pražnjenja čisto akustičkom neiterativnom metodom u energetskom transformatoru / Algorithm for calculating influence of power transformer oil temperature change on the accuracy of allacoustic non-iterative partial discharge localization
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2018)
Ovaj rad razmatra čisto akustičku metodu za lokalizaciju parcijalnog pražnjenja u energetskom transformatoru. Ova metoda se zasniva na matematičkom modelu koji koristi multilateraciju, princip vremenske razlike kašnjenja ...
Fatigue life analysis of the integral skin-stringer panel using xfem
(Institut za ispitivanje materijala, Beograd, 2017)
Fatigue life of integral skin-stringer panels produced by laser beam welding (LBW) is analysed. This type of panel is used in airframe construction where fatigue and damage tolerance are of paramount importance, since ...

(Univerzitet u Nišu, Niš, 2018)
U radu je prikazana procedura evaluacije seizmičkih performansi interakcije šip-tlo inkrementalnom nelinearnom dinamičkom analizom (INDA -Incremental Nonlinear Dynamic Analysis). Ulazni signal u sistemu je tretiran preko ...
Impact of temperature and exploitation time on plane strain fracture toughness, k-ic, in a welded joint
(Institut za ispitivanje materijala, Beograd, 2017)
This paper presents the analysis of the impact of temperature and exploitation time on the tendency toward brittle fracture of welded joint constituents of new and exploited low-alloyed Cr-Mo steel A-387 Gr. B, by using ...
Simulation of fatigue crack growth in a2024-t351 t-welded joint
(Institut za ispitivanje materijala, Beograd, 2017)
Fatigue crack growth in friction stir welded T joints under three point bending is simulated numerically using the Extended Finite Element Method (XFEM). Three point bending fatigue load stress is applied at the centre of ...
Numerical analysis of stress and strain state of structural elements of container terminal
(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 ...
