Effect of microstructure on tensile properties of austenite-ferrite welded joint
(Faculty of Metallurgy, 2015)
Complex microstructure of austenite-ferrite welded joint has been investigated, focused on its influence on Focal tensile properties. Tensile properties (yield strength and hardening coefficient) have been evaluated by ...
Numerical analysis of stress distribution in polycrystalline microstructure
(Institut za ispitivanje materijala, Beograd, 2015)
The paper presents a numerical analysis of stress distribution in micromechanical models in order to simulate microstructural mechanisms of microcrack initiation and propagation in polycrystalline metals. The analysis is ...
Numerical analysis of anchored bored piles in fractured rock masses
(ICE Publishing, 2015)
Grdelicka gorge, through which upcoming Motorway E-75 will pass by, is made of very old rock masses, influenced by strong tectonic forces and severe physical, chemical and erosion processes. The oldest and most frequents ...
Neka od dostignuća u implementaciji RBIM u skladu sa RIMAP pristupom / Some achievements in RBIM implementation according to RIMAP approach
(Institut za ispitivanje materijala, Beograd, 2015)
Some results of RIMAP based RBIM implementation on the example of 21 000 components in refinery Pancevo are presented in this paper. It is proved to be a powerful tool for maintenance planning, for increasing industrial ...

Merenje i analiza vibracija aksijalnog kompresora izazvanih nestabilnim protokom vazduha kroz uvodnik tokom leta aviona / Izmerenie i analiz vibracij osevogo kompressora, obuslovlennyh nestabil'nym potokom vozduha čerez vozduhozabornik samoleta vo vremja poleta / (francuski) Mesurage et analyse des vibrations du compresseur axial provoquées par le courant instable de l'air par le tuyau d'arrivée pendant le vol d'avion
(Vojnotehnički institut, Beograd, 2015)
U radu je prezentovan praktičan primer merenja i analize vibracija na prva dva stepena aksijalnog kompresora sa namerom da se proceni povezanost između poremećene ulazne struje vazduha i pojave otcepljenja strujnica od ...
Analysis of causes of degradation of parent material and weld metal of breeches pipe at hydro power plant 'Perućica'
(Institut za ispitivanje materijala, Beograd, 2015)
Presented are results of non-destructive tests performed on the parent material and welded joints of structural parts of a breeches pipe (collar and anchor), and results of destructive tests performed on the parent material ...
Crack resistance of aluminium alloy friction stir welded joint
(Institut za ispitivanje materijala, Beograd, 2015)
Charpy testing is conducted on a high-speed data acquisition instrument, using instrumented pendulum to separate energies for crack initiation and propagation. The J-R curves are used to determine JIc, as the measure of ...
Failure resistance of drilling rig casing pipes with an axial crack
(Pergamon-Elsevier Science Ltd, Oxford, 2015)
Working conditions of casing pipes in drilling rigs can significantly influence the initiation and development of damage in the material, and therefore also the safe service of the entire system. In this work, an integrity ...
Bond strength of restorative materials to hydroxyapatite inserts and dimensional changes of insert-containing restorations during polymerization
(Elsevier Sci Ltd, Oxford, 2015)
Objective. To determine the shear bond strength (SBS) between synthetic controlled porous hydroxyapatite (HAP) inserts and restorative materials and dimensional changes of insert-containing restorations during curing. ...
