Change of temperature and vertical force during friction stir welding / Promena temperature i vertikalne sile tokom procesa zavarivanja trenjem mešanjem
(DUZS - Društvo za unapređivanje zavarivanja u Srbiji, Beograd, 2013)
The aim of this paper is to analyze changes of vertical force and temperature during friction stir welding process of high strength aluminum alloys (2024 T3). FSW process is a complex nonlinear process accompanied by large ...
Characterisation of biocompatible layers of ZrO28%Y2O used in combination with other ceramics to modify the surface of implants / Karakterizacija biokompatibilnih slojeva ZrO28%Y2O3 koji se koriste u kombinaciji sa drugom keramikom za modifikaciju površine implantata
(Inženjersko društvo za koroziju, 2021)
The aim of this study was to deposit multi-functional ZrO28%Y2O3 coating layers using the plasma spray technology and then to characterise such layers. In combination with other biomedical ceramics, this coating is intended ...
Titanium dioxide nanoparticles surface modified with imine as fillers for epoxy resin / Nanočestice titan-dioksida površinski modifikovane iminom kao punioci za epoksidnu smolu
(Univerzitet u Nišu - Tehnološki fakultet, Leskovac, 2018)
The surface of anatase TiO2 nanoparticles was modified with in situ synthesized imine, based on 3,4-dihydroxybenzaldehyde and octadecylamine. The modified TiO2 nanoparticles were investigated using FTIR and UV-Vis spectroscopy, ...
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 ...
