Numerical aspects for efficient welding computational mechanics
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
The effect of the residual stresses and strains is one of the most important parameter in the structure integrity assessment. A finite element model is constructed in order to simulate the multi passes mismatched submerged ...
Višeciljna fazi optimizacija veličine i položaja piezoelektričnih aktuatora i senzora za upravljanje vibracijama bazirana na optimizaciji rojem čestica (deo 1: teorijski model) / Mul'ticelevaja faza optimizacii razmera i raspoloženija p'ezoëlektričeskih privodov i datčikov dlja upravlenija vibracijami na osnove optimizacii roja častic (čast' 1: teoretičeskaja model') / (francuski) Optimisation 'fuzzy' multi objective de la taille et de la location des actuaires piézoélectriques et des capteurs pour le contrôle des vibrations basée sur l'optimisation par essaim des particules (première partie: modèle théorétique)
(Vojnotehnički institut, Beograd, 2014)
Određivanje veličine i položaja piezoelektričnih aktuatora i senzora za aktivno upravljanje vibracijama savitljivih struktura obično je bazirano na maksimalnoj efikasnosti upravljanja i postizanja maksimalnog izlaza za ...
Interfacial crack behavior in the stationary temperature field conditions
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
The brittle coatings, made of different materials, when subjected to elevated temperatures and in the heat exchange conditions, are susceptible to delamination. Those coatings, as well as thin films, can be used for various ...
The initial analysis of the river Ibar temperature downstream of the lake Gazivode
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
As a result of a very limited number of geometric and other input data, the temperature modeling of the river Ibar downstream of the lake Gazivode was started by analyzing one river reach between Pridvorica, secondary dam ...
Structural, mechanical and tribological characterization of Zn25Al alloys with Si and Sr addition
(Elsevier Sci Ltd, Oxford, 2014)
The ZA-27 alloy is a zinc-aluminium casting alloy that has been frequently used as the material for sleeves of plain bearings. It has good physical, mechanical and tribological properties. However, one of the major ...
Remaining life assessment of a high pressure turbine casing in creep and low cycle service regime
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
Thick walled components such as high pressure (HP) steam turbine casings operating under high parameter conditions are subjected to a complex stress state. As a result of that stress state, some parts of HP turbine casing ...
Influence of furnace tube shape on thermal strain of fire-tube boilers
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
The aim of this paper is to use numerical analysis and fine element method-FEM to investigate the influence of furnace tube shape on the thermal strain of fire-tube boilers. Thermal stresses in corrugated furnace tubes of ...
Bosnia and Herzegovina's metalworking industry companies barriers to export to EU market
(Univerzitet u Novom Sadu - Tehnički fakultet Mihajlo Pupin, Zrenjanin, 2014)
Export of products and services on EU market can bring great benefits, but also sets requirements to companies which are not easy to meet. Metal processing industry today is the main exporter in Bosnia and Herzegovina ...
Impact Toughness of Friction Stir Welded Al-Mg Alloy
(Carl Hanser Verlag, Munich, 2014)
Al-Mg 5083 alloy was friction stir welded by varying welding variables, i.e., rotational speed, traversal speed and tool tilt angle. Welded specimens have been tested by the instrumented Charpy test to evaluate total ...
Bim: Promises and reality
(Institut za arhitekturu i urbanizam Srbije, Beograd, 2014)
The building information modeling - BIM is a technology developed toward creation of computer based information model that encompasses whole building lifecycle. Toward that goal a number of information technology standards ...
