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. ...
The influence of microstructure on ductile fracture initiation in low-alloyed steel
(Trans Tech Publications Ltd, Durnten-Zurich, 2004)
In this paper the quantitative microstructural analysis of low-alloyed pressure vessel steel has been discussed. The values of volume fraction and mean free path of non-metallic inclusions determined in that way were used ...
Heat pump supplemental heating system for motor vehicles
(Sage Publications Ltd, London, 2004)
The paper deals with the importance of supplemental heating of motor vehicles and the possibilities of automotive heat pump system utilization. A prototype heat pump system for motor vehicles has been developed, built in ...
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 ...

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 ...
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 ...
