The influence of corrosion on stress concentration factor at shaft to flange radius
(Springer Netherlands, 2013)
This paper describes the influence of corrosion on stress concentration factor and crack initiation at shaft-flange transition section. The real turbine shaft failure case study is used for research. This case study and ...
Verovatnoća greške po kanalu na bazi MGF metode korišćenjem Rician feding kanala za MPSK / Error probabilities in a channel based on MGF method using Rician fading for MPSK
(Savez inženjera i tehničara Srbije, Beograd, 2013)
U ovom radu se analizira verovatnoća greške po simbolu (Symbol Error Probability, SEP) fazno modulisanog (M-ary Phase Shift Keying, MPSK) signala u ambijentu frekventno-neselektivnog sporog Rician fedinga i prijemnika ...
Modern approach experimental verification of numerical models for tensile tests of welded specimens
(Croatian Society of Mechanics, 2013)
Ocena integriteta rezervoara sa mikroprslinama u zavarenom spoju / Integrity assessment of tanks with microcracks in welded joints
(Institut za ispitivanje materijala, Beograd, 2013)
Tokom eksploatacije rezervoara za skladištenje tečnog ugljendioksida ukazala se potreba za ugradnjom dva nova priključka u jedno od danaca. Rezervoar je izrađen od mikrolegiranog čelika, a priključci od visokolegiranog ...
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 ...
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 ...
