Free vibration of structures composed of rigid bodies and elastic beam segments
(Academic Press Ltd- Elsevier Science Ltd, London, 2015)
Free vibration of structures composed of rigid bodies and elastic beam segments is considered, assuming that the mass centers of rigid bodies are not located on the neutral axes of undeformed elastic beam segments. It is ...
Failure analysis of an aircraft engine cylinder head
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
The piston engine of the training aircraft malfunctioned during the flight due to the cracking of its cylinder head (CH), which is manufactured from an aluminum casting alloy. Based on the fractographic examination of the ...
Error bounds of Micchelli-Rivlin quadrature formula for analytic functions
(Academic Press Inc Elsevier Science, San Diego, 2013)
We consider the well known Micchelli-Rivlin quadrature formula, of highest algebraic degree of precision, for the Fourier-Chebyshev coefficients. For analytic functions the remainder term of this quadrature formula can be ...
Active boundary layer control in linear cascades using CFD and artificial neural networks
(Elsevier France-Editions Scientifiques Medicales Elsevier, Issy-Les-Moulineaux, 2014)
Flow field in linear cascades under high subsonic/transonic conditions has been investigated numerically. Active boundary layer control was employed in the form of sources (jets) distributed across the upper surface of the ...
Kronrod extensions with multiple nodes of quadrature formulas for fourier coefficients
(Mathematics of Computation, 2014)
We continue with analyzing quadrature formulas of high degree of precision for computing the Fourier coefficients in expansions of functions with respect to a system of orthogonal polynomials, started recently by Bojanov ...
The influence of mechanical activation on the electrical properties of Ba0.77Sr0.23TiO3 ceramics
(Elsevier Sci Ltd, Oxford, 2014)
Ferroelectric barium strontium titanate (Ba0.77Sr0.23TiO3), BST, was prepared by solid-state reactions using as the starting compounds powder of barium carbonate (BaCO3), strontium carbonate (SrCO3) and titanium dioxide ...
Robust second-order PD type iterative learning control for a class of uncertain fractional order singular systems
(Sage Publications Ltd, London, 2016)
This paper presents a robust second-order feedback PD type iterative learning control (ILC) for a class of uncertain fractional-order singular systems. Sufficient conditions for the robust convergence of the proposed PD ...
Petrological and organic geochemical properties of lignite from the Kolubara and Kostolac basins, Serbia: Implication on Grindability Index
(Elsevier, Amsterdam, 2014)
The influence of different coal lithotypes on grindability has been investigated using lignite from two of the most important Upper Miocene lignite basins in Serbia (Kolubara and Kostolac). Yellow xylite-rich types ...
Plastic deformation and modification of surface characteristics in nano- and micro-levels and enhancement of electric field of FCC materials using cavitation phenomenon
(Elsevier, Amsterdam, 2016)
The aim of this paper is to demonstrate and establish a possible application of the cavitation phenomenon as an efficient method to modify surface properties. Three FCC (Face Centered Cubic) materials were subjected to ...
Creep crack growth properties of P91 and P22 welded joints
(Wiley, Hoboken, 2017)
The ferritic P22 and bainitic-martenstic P91 steel welded joints operating at elevated temperatures are highly vulnerable to premature failure, because microstructure gradients can lead to cracking in the heat-affected ...
