Physical and metallurgic changes during the friction welding of high-speed cutting steel and tempered steel
(Faculty of Mechanical Engineering in Slavonski Brod, Faculty of Electrical Engineering in Osijek, Faculty of Civil Engineering in Osijek, 2009)
This paper outlines the basic principles of welding by friction of high-speed cutting steel and tempered steel from the viewpoint of metallurgic processes that are going on in the material. The bases of welding by friction ...
Design update and mock-up test strategy for the validation of the eu-hcpb-tbm concept
(Taylor & Francis Inc, Philadelphia, 2009)
In the frame of the activities of the EU Breeder Blanket Programme and of the Test Blanket Working Group of ITER, the Helium Cooled Pebble Bed Test Blanket Module (HCPB-TBM) is developed to investigate DEMO relevant concepts ...
Failure analysis of the end eye connection of the bucket wheel excavator portal tie-rod support
(Pergamon-Elsevier Science Ltd, Oxford, 2009)
This paper describes the failure analysis results of the bucket wheel excavator (BWE) portal tie-rod support. The results of finite elements analysis (FEA) point out the occurrence of pronounced stress concentration, whereby ...
Determination of ductile crack initiation by magnetic emission and potential drop techniques using pre-cracked Charpy specimens
(European Structural Integrity Society, 2002)
Magnetic emission (ME) and potential drop (PD) techniques were used for instrumented Charpy impact testing in order to determine critical crack initiation properties of standard pre-cracked three-point bending specimens ...
Analysis of the transferability of micromechanical parameters of damage of steel under the conditions of ductile-fracture initiation
(Springer, New York, 2002)
For the description of the mechanical behavior of a cracked material, we use a macromechanical model of fracture based on the well-known criterion of plastic yield for porous materials. This model is realized as a computational ...

(Institut za istraživanja i projektovanja u privredi, Beograd, 2006)
Trying to estimate perspectives of Facility Management development in Serbia, the authors are looking for rare cases and initiations of Facility Management in practice, considering recent experiences from the countries in ...
Pro et contra primene ODA postupka za konzervaciju i čišćenje radnih površina termoenergetskih postrojenja / Pro et contra of ODA method for conservation and cleaning of working surfaces of power plants
(Visoka tehnička škola strukovnih studija, Beograd, 2005)
Najčešći oblik korozionog razaranja materijala, koji se javlja tokom dugih remontnih perioda i neplaniranih zastoja i u odsustvu odgovarajuće zaštite cevnog sistema kotla, je lokalna kiseonična korozija. Zbog toga je ...
Analiza i dijagnostika ponašanja struktura / Structure behavior analysis and diagnostic
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2005)
U radu je dat opis primene razvijene metodologije analize i dijagnostike ponašanja strukture. Osnova analize predstavlja statički, dinamički i termički proračun primenom metode konačnih elemenata. Navedena metodologija ...
Integritet cevovoda hidroelektrane / Integrity of penstock of hydroelectric powerplant
(Institut za ispitivanje materijala, Beograd, 2005)
Iskustvo iz eksploatacije cevovoda hidroelektrana ukazuje na moguće procurivanje posle stabilnog rasta prsline ili raspucavanje u slučaju krtog loma. Uvođenje zavarljivih čelika visoke čvrstoće za izradu cevovoda donosi ...
Procena integriteta zavarenih spojeva primenom inženjerskih metoda / Weldment structural integrity evaluation by using engineering methods
(DUZS - Društvo za unapređivanje zavarivanja u Srbiji, Beograd, 2002)
U radu je prikazana primena nekih inženjerskih metoda za procenu integriteta zavarenih spojeva. Razmatrana je, kao najopštija, procedura PD6493, sa posebnim osvrtom na mogućnost primene na zavarene spojeve, i procedure ...
