Numerical simulation of constraint effect on fracture initiation in welded specimens using a local damage model / Numerička simulacija uticaja veze na inicijaciju loma kod zavarenih epruveta upotrebom modela lokalnog oštećenja
(Society for Structural Integrity and Life, Institute for Material Testing, 2011)
In this paper, two micromechanical models: the Gurson-Tvergaard-Needleman (GTN) model and Complete Gurson Model (CGM) are used to predict ductile fracture initiation of two different welded specimens, SE(B) and C(T). The ...
Numerical analysis of thermal stresses in welded joint made of steels x20 and x22
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
Stress calculation of steam pipeline is presented, focused on the welded joint. Numerical calculation was peiformed using the finite element method to obtain stress distribution in the welded joint made while replacing the ...
Structural, ferroelectric and magnetic properties of BiFeO3 synthesized by sonochemically assisted hydrothermal and hydro-evaporation chemical methods
(Elsevier Sci Ltd, Oxford, 2016)
BiFeO3 powders were synthesized by sonochemically assisted hydrothermal and hydro-evaporation methods. The X-ray diffraction confirmed the presence of secondary phases, Bi25FeO39 and Bi2Fe4O9, in as prepared BiFeO3 powders. ...
The effect of T4 heat treatment on the microstructure and corrosion behaviour of Zn27Al1.5Cu0.02Mg alloy
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
The effect of heat treatment on the microstructure and corrosion behaviour of Zn27Al1 5CuO 02Mg alloy was examined The alloy was prepared by melting and casting route and then thermally processed (T4 regime) Corrosion ...
Pt nanoparticles on tin oxide based support as a beneficial catalyst for oxygen reduction in alkaline solutions
(Royal Society of Chemistry, 2015)
A platinum nanocatalyst on Sb doped tin oxide support (Sb-SnO2) was synthesized and characterized as a catalyst for oxygen reduction reaction in 0.1 mol dm(-3) NaOH solution at 25 degrees C. Sb (5%) doped tin oxide support ...
Cleaner production aspects of tablet coating process in pharmaceutical industry: problem of VOCs emission
(Elsevier Sci Ltd, Oxford, 2013)
The aim of the article is to present a case study related to implementation of cleaner production (CP) process with the concept of minimizing emissions versus the end of pipe (EOP) approach within pharmaceutical industry. ...
Modelling of dissolved oxygen in the Danube River using artificial neural networks and Monte Carlo Simulation uncertainty analysis
(Elsevier Science Bv, Amsterdam, 2014)
This paper describes the training, validation, testing and uncertainty analysis of general regression neural network (GRNN) models for the forecasting of dissolved oxygen (DO) in the Danube River. The main objectives of ...
Assessment of spatial and temporal variations in trace element concentrations using honeybees (Apis mellifera) as bioindicators
(Peerj Inc, London, 2018)
With the increase in anthropogenic activities metal pollution is also increased and needs to be closely monitored. In this study honeybees were used as bioindicators to monitor metal pollution. Metal pollution in honeybees ...
Pb(II) removal from aqueous solution by Myriophyllum spicatum and its compost: equilibrium, kinetic and thermodynamic study
(Wiley, Hoboken, 2014)
BACKGROUND Lead is one of the frequent contaminants of industrial wastewater. Since it has been shown that aquatic plants can be used for the removal of heavy metals, herein Pb(II) biosorption by Myriophyllum spicatum and ...
Ti substrate coated with composite Cr–MoO2 coatings as highly selective cathode materials in hypochlorite production
(Elsevier, 2013)
The aim of this work was to investigate the possibility of preparation of the composite Cr–MoO2 coatings onto steel and titanium substrates as cathode materials with high selective properties which imply the suppression ...
