(Faculty of Technology, Novi Sad, 2013)
The main objective of the research presented in this paper was to carry out a statistical-mechanical analysis concerning the tensile test of glass-epoxy composite materials in order to calculate their relevant tension ...
Corrosion properties of an aluminium alloy 7000 series after a new two step precipitation hardening / Otpornost prema koroziji aluminijumske legure serije 7000 posle novog dvostepenog termičkog taloženja
(Engineering Society for Corrosion, Belgrade, Serbia, 2014)
Corrosion properties of an aluminium alloy 7000 series were investigated by different electrochemical methods. The alloy was subjected to the one-step and to a new two-step precipitation hardening. Polarization measurements ...
Fluoride ion adsorption onto Al-alginate particles / Adsorpcija fluoridnih jona na Al-alginatnim česticama
(Engineering Society for Corrosion, Belgrade, Serbia, 2017)
Fluoride ions are increasingly present in the groundwater mainly due to the anthropogenic activity. On the other hand, increased awareness of harmful effects caused by high concentrations of F-in drinking water, leads to ...

(Engineering Society for Corrosion, Belgrade, Serbia, 2016)
This paper reports on progress in developing an effective method for internal pipeline corrosion control in the presence of CO2. The inhibition effect of talloil diethylenetriamine imidazoline (TOFA/DETA imidazoline) on ...
Simulation of velocity profile inside turbulent boundary layer
(Association of Metallurgical Engineers of Serbia, 2020)
The second-order differential equation with a general polynomial solution [1], is adapted for simulation of complex velocity profile inside the turbulent boundary layer. Consequently, the simulation strategy is suggested.
Indentation behaviour of 'soft film on hard substrate' composite system type / Ponašanje kompozitnih sistema tipa 'mek film na tvrdom supstratu' na testu utiskivanja
(Engineering Society for Corrosion, Belgrade, Serbia, 2015)
This investigation has been carried out in order to analyse and compare the hardness response of different composite systems of the same type, named 'soft film on hard substrate' composite system. Composite systems of mono- ...
