Finite element modelling of creep process - steady state stresses and strains
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
Finite element modelling of steady state creep process has been described. Using an analogy of visco-plastic problem with a described procedure, the finite element method has been used to calculate steady state stresses ...
Modeling of the buckstay system of membrane walls in watertube boiler construction
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
Membrane walls are very important structural parts of water-tube boiler construction. Based on their specific geometry, one special type of finite element was defined to help model the global boiler construction. That is ...
Eksperimentalno istraživanje 'spillover' efekta u sistemima aktivnog upravljanja vibracijama / Experimental investigation of spillover effect in system of active vibration control
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2014)
Piezoelektrični aktuatori se uveliko primenjuju za aktivno upravljanje vibracijama na raznim strukturama sa ciljem povećanja performansi sistema. Razvijeni sistem aktivnog upravljanja vibracijama se sastoji od aktivnije ...
Free vibration control of smart composite beams using particle swarm optimized self-tuning fuzzy logic controller
(Academic Press Ltd- Elsevier Science Ltd, London, 2014)
This paper deals with active free vibrations control of smart composite beams using particle-swarm optimized self-tuning fuzzy logic controller. In order to improve the performance and robustness of the fuzzy logic controller, ...
Wear of internal combustion engine parts with possibilities for their regeneration
(Expert Verlag, 2014)
Only 12% of the total energy of the fuel finds its way to the driving wheels, while 15% of it is being dissipated as mechanical, mainly frictional losses. These numbers could be improved by applying methods of reparation ...
Austempering Kinetics of Cu-Ni Alloyed Austempered Ductile Iron
(Korean Inst Metals Materials, Seoul, 2014)
The aim of the paper was to investigate the effect of austempering parameters (time and temperature) on the microstructure and mechanical properties of ADI alloyed with 1.5% Cu and 1.6% Ni (in wt.%) in order to establish ...
Numerical simulation of the pile integrity test on defected piles
(University of Maribor, 2014)
This paper deals with the development of a discrete numerical 2D and 3D solid pile model with a discontinuity and defects to simulate non-destructive testing using the pile integrity test (PIT). The pile discontinuity and ...
Izračunavanje verovatnoće greške po simbolu na bazi MGF metode korišćenjem Rician feding kanala za MFSK modulaciju / Calculating the probability of error per symbol on the basis of MGF method using Rician fading for MFSK
(Savez inženjera i tehničara Srbije, Beograd, 2014)
U ovom radu se analizira verovatnoća greške po simbolu za M-arnu ne-koherentnu frekvencijsku modulaciju (M-ary Frequency Shift Keying, MFSK) signala u ambijentu frekvencijsko-neselektivnog sporog Rician fadinga i prijemnika ...
Isogeometric bending analysis of composite plates based on a higher-order shear deformation theory
(Korean Soc Mechanical Engineers, Seoul, 2014)
This research paper presents an isogeometric plate finite element formulation for analysis of thick composite plates. Isogeometric finite element method which is based on non-uniform rational B-splines (NURBS) basis ...
Potential for improvement of comfort parameters in off-road vehicles of Serbian armed forces
(Strojarski Facultet, 2014)
The paper presents the comparative results of comfort parameter testing inside the cabin of Land Rover Defender off-road vehicles. The measurements were carried out on two vehicle models -110 GS Hard Top and 110 GS Soft ...
