Analysis of the properties of a Cu-Al2-O3 sintered system based on ultra fine and nanocomposite powders
(International Institute for the Science of Sintering, Beograd, 2007)
In this paper synthesis of a composite based on Cu-Al2O3 by a thermo-chemical method is shown along with a comparative analysis of the properties of the obtained nanocomposite sintered samples, which are characterized by ...
Numerical method for the prediction of bending properties of glass-epoxy composites / Primena numeričkog modela za predviđanje savojnih svojstava staklo-epoksi kompozitnog materijala
(Faculty of Technology, Novi Sad, 2007)
Mechanical properties of composite materials are conditioned by their structure and depend on the characteristics of structural components. In this paper is presented a numerical model by which the bending properties can ...
Significance and application of geothermal waters of Jošanica spa / Značaj i primena geotermalnih voda Jošaničke Banje
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd i Društvo termičara Srbije, Beograd, 2007)
Geothermal energy takes important place in application of alternative energy sources. Geothermal energy is promising energy source, ecological safe because it belongs to renewable energy resources. Potential of geothermal ...
The influence of antioxidant and post-synthetic treatment on the properties of biodegradable poly(butylene succinate)s modified with poly(propylene oxide) / Uticaj antioksiodansa i načina izdvajanja polimera na svojstva biodegradabilnih poli(butilen sukcinata) modifikovanih poli(propilenoksidom)
(Serbian Chemical Society, Belgrade, 2007)
Novel poly(ester-ether)s based on poly(butylene succinate) (PBS) as the hard segments and 30 mass % of poly(propylene oxide) (PPO) as the soft segments were synthesized with varying amount of the antioxidant (N,N'-diphen ...
A model for predicting fracture toughness in overaged 7000 alloy forgings
(Savez inženjera metalurgije Srbije, Beograd, 2007)
An attempt to develop a multiple micromechanism-based model for predicting plane-strain fracture toughness, KIc, of overaged 7000 alloy forgings has been made. The proposed model reveals the quantitative relations between ...
Micromechanical analysis of constraint effect on fracture initiation in strength mismatched welded
(Trans Tech Publications Ltd, Durnten-Zurich, 2007)
In this paper the micromechanical approach to ductile fracture was applied in a study of constraint effect on crack growth initiation in mismatched welded joints. The single-edged notched bend specimens (precrack length ...
Phenomenology of a formation of a honeycomb-like structure during copper electrodeposition
(Journal of Solid State Electrochemistry, 2007)
In this paper, the phenomenology of a formation of a honeycomb-like structure was considered. Copper deposits obtained at overpotential of 1000 mV were examined by scanning electron microscopy (SEM) technique. It was shown ...
