Dijagnostika čvrstoće konstrukcije / Structural performance diagnostics
(Institut za ispitivanje materijala, Beograd, 2004)
Dijagnostika čvrstoće konstrukcija predstavlja osnovu sanacija i rekonstrukcija opreme. Ona obuhvata analizu stanja, ponašanja i popuštanja konstrukcije, kao i procenu preostale čvrstoće, radnog veka, režim rada i obim ...
Modeliranje i parametarska analiza rada ložišta energetskog kotla / Modeling and parametric study of utility boiler furnace operation
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd i Društvo termičara Srbije, Beograd, 2004)
U radu su prikazani odabrani rezultati parametarskih proračuna izvedenih na osnovu numeričke simulacije procesa u ložištu za sagorevanje ugljenog praha energetskog kotla TENT-A2 210 MWe, sa odvođenjem šljake u čvrstom ...
Analysis of the unstable fracture behaviour of a high strength low alloy steel weldment
(Pergamon-Elsevier Science Ltd, Oxford, 2004)
Local brittle zones (LBZ) cause the unstable fracture behaviour of weld metals. This threatens the safe service of welded structures and makes structural assessment procedures difficult. Therefore, the unstable fracture ...
Micromechanical coupled study of crack growth initiation criterion in pressure vessel steel
(Strength of Materials, 2004)
We present results of the combined design-theoretical investigation of the mechanism of crack growth at the onset of ductile fracture of NPP reactor pressure vessels. Micromechanical approach to the prediction of ductile ...
Razvoj opreme za proizvodnju peleta od biomase / Development of equipment biomass pellets production
(Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije (SMEITS), Beograd, 2004)
S obzirom da biomasa predstavlja obnovljivi vid energije, a da je cena električne energije kao i fosilnih goriva sve veća, došlo je do povećane zainteresovanosti za izradu i nabavku opreme za proizvodnju peleta. Agrarni ...
Prediction of ductile fracture initiation using micromechanical analysis
(Pergamon-Elsevier Science Ltd, Oxford, 2004)
In the paper ductile fracture initiation analysis of low-alloyed ferritic steel has been made by application of two micromechanical models: the Rice-Tracey void growth model and the Gurson-Tvergaard-Needleman (GTN) model. ...
Group theoretical formulation of quadrilateral and hexahedral isoparametric finite elements
(Pergamon-Elsevier Science Ltd, Oxford, 2004)
The group supermatrix procedure, developed by Zlokovic, is applied for derivation of stiffness matrices of quadrilateral and hexahedral isoparametric finite elements using the symmetry groups C-2v and D-2h respectively. ...
Procena integriteta zavarene konstrukcije oblika ploče sa prslinom / Structural integrity assessment of welded plate with a crack
(Institut za ispitivanje materijala, Beograd, 2004)
Analiziran je uticaj geometrije (položaj prsline, dimenzije i oblik zavarenog spoja, dimenzija uzorka) i heterogenosti materijala na ponašanje i ocenu integriteta zavarenih ploča. Eksperimentalnom analizom obuhvaćene su ...
Microstructure and toughness of CuNiMo austempered ductile iron
(Elsevier, Amsterdam, 2004)
The effect of austempering on the microstructure and toughness of nodular cast iron (designated as CuNiMoSG) alloyed with molybdenum, copper, nickel, and manganese has been studied. Light microscopy (LM), scanning electron ...
Micromechanical coupled study of crack growth initiation criterion in Pressure vessel steel
(Problemy Prochnosti, 2004)
We present results of the combined design-theoretical investigation of the mechanism of crack growth at the onset of ductile fracture of NPP reactor pressure vessels. Micromechanical approach to the prediction of ductile ...
