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 ...
Calculation of maximum tensile and shear forces in restorative materials using finite element method
(Trans Tech Publications Ltd, Durnten-Zurich, 2014)
The purpose of this paper was to determine tensile loading that leads to dental restoration failure, i.e. the critical values of stress. In order to analyze stress distribution within the restoration and tooth, mechanical ...
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 ...
Finite element modelling of creep process - steady state stresses and strains
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
Finite element modelling of steady state creep process has been described. Using an analogy of visco-plastic problem with a described procedure, the finite element method has been used to calculate steady state stresses ...
Modeling of the buckstay system of membrane walls in watertube boiler construction
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
Membrane walls are very important structural parts of water-tube boiler construction. Based on their specific geometry, one special type of finite element was defined to help model the global boiler construction. That is ...
Eksperimentalno istraživanje 'spillover' efekta u sistemima aktivnog upravljanja vibracijama / Experimental investigation of spillover effect in system of active vibration control
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2014)
Piezoelektrični aktuatori se uveliko primenjuju za aktivno upravljanje vibracijama na raznim strukturama sa ciljem povećanja performansi sistema. Razvijeni sistem aktivnog upravljanja vibracijama se sastoji od aktivnije ...
Local Strain and Stress Analysis of Globe Valve Housing Subjected to External Axial Loading
(Trans Tech Publications Ltd, Durnten-Zurich, 2014)
Globe valves have widespread application in various industrial sectors. Due to this variety, valve is subjected to different working loads (static, dynamic, thermal etc.) that can cause valve failures. In this paper, the ...
