Measurement of local deformation fields in dental composites using 3d optical system
(Chemicke Listy, 2011)
Polymerization shrinkage is the single most important local deformation of dental composites that has a substantial effect on the quality of the tooth-restoration interface in clinical conditions. The aim of this study was ...
Influence of forward scattering on prediction of temperature and radiation fields inside the pulverized coal furnace
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
A possibility of simplification of the scattering phase function of a pulverized coal flame was analyzed in the paper. It was showed that the type of radiation scattering of a pulverized coal flame is between two limiting ...
Fatigue Life Estimation of Notched Structural Components
(Assoc Mechanical Engineers Technicians Slovenia, Ljubljana, 2010)
This work considers the analytical/numerical methods and procedures for obtaining the stress intensity factors and for predicting the fatigue crack growth life of notched structural components. Many efforts have been made ...
Surface characterisation of Pb1-XMnXTe alloy by atomic force microscopy and magnetic force mode
(MANEY PUBLISHING, LEEDS, 2011)
In this paper the authors present the results of surface characterisation of a lead telluride alloy conducted by atomic force microscopy and magnetic force microscopy. Relationship between surface morphology, in the range ...

Practical aspects of fail-safe design - calculation of fatigue life of cracked thin-walled structures
(Faculty of Mechanical Engineering in Slavonski Brod, Faculty of Electrical Engineering in Osijek, Faculty of Civil Engineering in Osijek, 2011)
This paper represents fatigue crack growth life prediction in thin-walled structures (plates or shells). There are two analysis results from two different packages of software: NASGRO and FRANC 3D. They are based on Finite ...
Uticaj zaštitnog gasa na žilavost metala šava legure AlMg4.5Mn dobijenog postupkom zavarivanja cirkulacijom / The effect of shielding gas on the toughness of AlMg4.5Mn weld metals made by GMAW
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2011)
Analiziran je uticaj zaštitnog gasa, na žilavost metala šava aluminijumske legure AlMg4.5Mn dobijenog MIG/MAG postupkom zavarivanja. Za merenje žilavosti je korišćeno instrumentirano Šarpijevo klatno sa mogućnošću razdvajanja ...
Numerička simulacija faze uranjanja kod zavarivanja trenjem mešanjem / Numerical simulation of the plunge stage in friction stir welding
(Institut za ispitivanje materijala, Beograd, 2011)
U ovom radu je istražena faza uranjanja alata primenom numeričkog modeliranja. Trodimenzionalni model konačnih elemenata (FEM) faze uranjanja je razvijen primenom softvera ABAQUS radi proučavanja termomehaničkih procesa ...
