Butt welded joints assessment after fire exposure
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
The need of in service life of a steel structure after being exposed to fire raises the problem of strengthening or replacement of some structural elements. In many cases, after structural safety assessment, fire exposed ...
Effect of laser beam welded reinforcement on integral skin panel fatigue life
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
In this paper, numerical analyses of fatigue crack growth in integral skin-stringer panel produced by means of laser beam welding (LBW) are presented along with fatigue results verified by previously conducted experiments. ...
Experimental and numerical investigations of heat transfer in the first wall of Helium-Cooled-Pebble-Bed Test Blanket Module Part 2: Presentation of results
(Elsevier Science Sa, Lausanne, 2015)
This paper is the continuation of the first report on investigations of heat transfer in the first wall of Helium-Cooled-Pebble-Bed Test Blanket Module for ITER submitted to this Journal (see Ilic et al. [ID. The investigations ...
Experimental studies on active vibration control of a smart composite beam using a PID controller
(IOP Publishing Ltd, Bristol, 2013)
This paper presents experimental verification of the active vibration control of a smart cantilever composite beam using a PID controller. In order to prevent negative occurrences in the derivative and integral terms in a ...
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 ...
Failure investigation of the bucket wheel excavator crawler chain link
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
The high mobility of open pit machines in heavy duty conditions provides fertile ground for the occurrence of various failures of the traveling mechanisms' vital parts such as chain links. The goal of the study presented ...
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 ...
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 ...
Experimental and numerical investigations of heat transfer in the first wall of Helium-Cooled-Pebble-Bed Test Blanket Module - Part 1: Presentation of test section and 3D CFD model
(Elsevier Science Sa, Lausanne, 2015)
This paper deals with cooling of the first wall of Helium-Cooled-Pebble-Bed Test Blanket Module (HCPB TBM) for ITER. The first wall cooling is an important investigation issue due to an extreme asymmetry of heat loads: ...
