Spregnuti nelinearni problemi u analizi konačnim elementima - studija slučaja / Coupled nonlinear problems in finite element analysis: A case study
(Integritet i vek konstrukcija, Beograd, 2012)
Rad daje opis analize elastoplastičnih deformacija čeličnog cevnog apsorbera kinetičke energije sudara železničkih vozila metodom konačnih elemenata (FEM). Eksperimentalna istraživanja korišćena su kao osnova za modeliranje ...
Uporedna analiza proračuna mašinskih elemenata simuliranjem kombinovanog opterećenja i odvojenim simuliranjem komponentnih opterećenja - studija slučaja / Combined load simulation vs component loads simulation in machine design: A case study
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2014)
Na sadašnjem nivou razvoja tehnologije, u stvarnim radnim uslovima, gotovo svi mašinski elementi su opterećeni kombinovanim opterećenjima. Cilj istraživanja prikazanog u ovom radu je ukazivanje na značaj proračuna nosivosti ...
Izbor optimalnog dodatnog materijala za reparaturno zavarivanje vratila turbine hidrocentrale na licu mesta / Selection of the optimal filler material for on-site repair welding of the turbine shaft at the hydropower plant
(DUZS - Društvo za unapređivanje zavarivanja u Srbiji, Beograd, 2011)
Najznačajniji delovi hidroelektrana, vratila turbina izložena su tokom rada visokim naprezanjima, puzamju, zamoru i koroziji. Zbog toga je korisno preduprediti oštećenja tokom rada, povećati pouzdanost i produžiti radni ...
Influence of defects on limit loads and integrity of the pipeline at hydropower plant 'Pirot'
(Institut za ispitivanje materijala, Beograd, 2020)
Topic of this work is the integrity assessment of the pipeline section from hydropower plant Pirot. Crack-like defect size, maximum depth, is determined based on non-destructive evaluation - the largest crack depth is taken ...
Imobilizacija teških metalnih jona Zn2+, Ni2+, Pb2+ i Cu2+ u strukturi materijala na bazi cementa / Immobilization of heavy metal ions Zn2+, Ni2+, Pb2+ and Cu2+ in the structure of cement-based materials
(Inženjersko društvo za koroziju, Beograd, 2020)
Prirodni zeolit i bentonit korišćeni su kao mineralni dodaci u mešavinskom dizajnu ekološki sigurnih građevinskih materijala na bazi cementa. Ispitane su adsorptivne sposobnosti ove dve glinene sirovine, tj. njihov afinitet ...
