Structural, mechanical and tribological characterization of Zn25Al alloys with Si and Sr addition
(Elsevier Sci Ltd, Oxford, 2014)
The ZA-27 alloy is a zinc-aluminium casting alloy that has been frequently used as the material for sleeves of plain bearings. It has good physical, mechanical and tribological properties. However, one of the major ...
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, ...
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 ...
Experimental studies on active vibration control of smart plate using a modified PID controller with optimal orientation of piezoelectric actuator
(Sage Publications Ltd, London, 2016)
This paper presents a design, development and experimental verification of an active vibration control system of aluminum plate. The active structure consists of an aluminum rectangular plate as the host structure, strain ...
An attempt to create a standardized (reference) model for experimental investigations on implant's sample
(Elsevier Sci Ltd, Oxford, 2015)
The aim of this study was to determine, evaluate and measure strain of vertically loaded implant using the digital image correlation method. The Straumann (R) dental implant system with the SLActive (R) surface was used ...
Geometry, mechanical and ballistic properties of ADI material perforated plates
(Elsevier Sci Ltd, Oxford, 2015)
In this paper, austempered ductile iron has been evaluated as an alternative to steel for perforated plates applied in the ballistic protection of military vehicles. The austempering was performed in lower and higher ...
Picosecond Laser Shock Peening of Nimonic 263 at 1064 nm and 532 nm Wavelength
(MDPI, Basel, 2016)
The paper presents a study on the surface modifications of nickel based superalloy Nimonic 263 induced by laser shock peening (LSP) process. The process was performed by Nd3+:Yttrium Aluminium Garnet (YAG) picosecond laser ...
Stringer effect on fatigue crack propagation in A2024-T351 aluminum alloy welded joint
(Elsevier Sci Ltd, Oxford, 2017)
This paper describes fatigue crack growth in a friction stir welded T joints made of aluminum alloy A2024-T351 under three point bending loads. For this purpose, three dimensional homogeneous isotropic model is used to ...
Fracture assessment of seam and seamless steel pipes by application of the ring-shaped bending specimens
(Elsevier, Amsterdam, 2019)
The topic of this work is analysis of fracture behaviour and resistance of the thin-walled seamless and seam steel pipes, through application of the recently proposed ring-shaped specimen (PRNB - Pipe Ring Notched Bend). ...
Optimal vibration control of smart composite beams with optimal size and location of piezoelectric sensing and actuation
(Sage Publications Ltd, London, 2013)
Control performances of smart structures depend on the size and location of the piezoelectric actuators and sensors as well as on the applied control algorithm. This article presents optimal vibration control of a thin-walled ...
