Modelling of ductile fracture initiation in strength mismatched welded joint
(Pergamon-Elsevier Science Ltd, Oxford, 2008)
In this paper, the effect of strength mismatch and width of the welded joints oil the stress-strain distribution in the crack tip region has been discussed. The single-edge notched bend (SENB) specimens (precrack length ...
Analysis of fouling factor in district heating heat exchangers with parallel helical tube coils
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
This paper presents the results of measurements of thermal performance of 8 heat exchangers with parallel helical coils. Measurements were conducted in substations in 2 district heating systems in Serbia: Belgrade and ...
Simultaneous consideration of contingency factors and quality management: An empirical study of Serbian companies
(Academic Journals, Victoria Island, 2011)
The aim of the present paper is to answer whether the QM concept is universal or context-dependent, organic or mechanistic, and theoretical or practical in its essence. The study examines the impact of contingency factors ...
Analysis of local shrinkage patterns of self-adhering and flowable composites using 3D digital image correlation
(Quintessence International, 2011)
Objective: To analyze local shrinkage patterns in terms of surface shrinkage strains and z-axis displacements in a novel self-adhering composite and a conventional flowable composite using three-dimensional digital image ...
Groundwater heat pump selection for high temperature heating retrofit
(Elsevier Science Sa, Lausanne, 2012)
Retrofitting of fossil fuel powered hot water radiator heating systems of the existing buildings by groundwater heat pumps can provide significant energy savings followed by economic and environmental benefits. The paper ...
Austempering study of unalloyed and alloyed ductile irons
(MANEY PUBLISHING, LEEDS, 2010)
Austempered ductile iron (ADI) proved to be an advanced material as it possesses remarkable combination of high strength, ductility and toughness with good wear resistance and machinability. These properties can be achieved ...
Methodology of physical occurrences analogy in researching vehicle lifetime
(Technics Technologies Education Management, 2011)
Lifetime as a critical dimension of the quality of a product is most often studied using the unreliability curve, when there are problems in determining the origin in terms of time limit (Delta t), since monitoring usually ...

The austempering study of alloyed ductile iron
(Elsevier Sci Ltd, Oxford, 2006)
Austempered ductile iron (ADI) proved to be an excellent material as it possesses attractive properties: high strength, ductility and toughness are combined with good wear resistance and machinability. These properties can ...
A computer code for the prediction of mill gases and hot air distribution between burners' sections at the utility boiler
(Pergamon-Elsevier Science Ltd, Oxford, 2008)
One of the main tasks during the design or simulation and analyses of the utility steam boiler operation is the prediction of a distribution of mill gases and hot air flow rates between burners' sections. These are the ...
