Uncertainty evaluation of the conducted emission measurements
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2013)
For the evaluation of measurement uncertainty in measuring the conduction emission, in this paper we propose a new model which uses mixed distribution. Evaluation of probability density function for the measurand has been ...
Stress concentration on the contour of a plate opening: analytical, numerical and experimental approach
(Polish Society of Theoretical and Allied Mechanics, 2013)
The objective of the paper is to analyze the stress concentration factor (SCF) in the corner of a rectangular plate opening with small radii of curvature and various methods for its derivation. Besides the finite element ...
Compatibility of fracture mechanics parameters and fatigue crack growth parameters in welded joint behaviour evaluation
(Strojarski Facultet, 2013)
Problem of fracture toughness, K-Ic, determination on a crack tip localized in a welded joint is set in principle, since fracture mechanics presumes homogeneous material, not only in a crack tip surrounding but on a distance ...
Active vibration control of smart composite beams using pso-optimized self-tuning fuzzy logic controller
(Polish Society of Theoretical and Allied Mechanics, 2013)
This paper presents the optimized fuzzy logic controller (FLC) with on-line tuning of scaling factors for vibration control of thin-walled composite beams. In order to improve the performances and robustness properties of ...
Promena temperature i vertikalne sile tokom procesa zavarivanja trenjem mešanjem / Change of temperature and vertical force during friction stir welding
(DUZS - Društvo za unapređivanje zavarivanja u Srbiji, Beograd, 2013)
Cilj rada je analiza promene vertikalne sile i temperature tokom procesa zavarivanja trenjem mešanjem (FSW) legura aluminijuma visoke čvrstoće (2024 T3). FSW postupak je složen nelinearan proces praćen velikim plastičnim ...
Experimental stress-strain analysis of composite beams
(Croatian Society of Mechanics, 2013)
Assessment of the effect of pitting corrosion on fatigue crack initiation in hydro turbine shaft
(Trans Tech Publications Ltd, 2013)
Energy efficiency is a key issue worldwide, and not confined solely to the realm of engineers. Past failures of mechanical power system components must be examined carefully in order to minimise future occurrences and ...
Tribological aspects of ballroom dance as a human activity with energy consumption analysis
(Journal of the Balkan Tribological Association, 2013)
Tribology phenomena are obviously present and have significant importance in most of human activities, processes and actions. This paper presents an attempt in this direction dealing with study of tribology aspects in ...
Application of digital image correlation in dentistry
(Croatian Society of Mechanics, 2013)
Microstructures and mechanical properties of creep resistant steel for application at elevated temperatures
(Elsevier Sci Ltd, Oxford, 2013)
The subject of this paper is the microstructural and mechanical characterisation of regions of the heat-affected zone (HAZ) in steels containing 9-12% Cr that are used for operation at elevated temperatures. Tests were ...
