Remaining strength of API J55 steel casing pipes damaged by corrosion
(Elsevier Sci Ltd, Oxford, 2020)
Experimental investigation of the integrity of casing pipes, used in the oil drilling rigs, withdrawn after about 70,000 h of service, has been conducted, together with numerical simulation. Pipes were manufactured by the ...
Microstructure and Wear Behavior of MMC Coatings Deposited by Plasma Transferred Arc Welding and Thermal Flame Spraying Processes
(Springer India, New Delhi, 2020)
In this study, two erosion protection MMC coatings with WC particles were deposited by the plasma transferred arc (PTA) welding. One of the coatings with tungsten carbide WC in the NiBSi matrix (WC/NiBSi), and the second ...
Experimental verification of performance of tip-jet helicopter propulsion system
(Elsevier, Amsterdam, 2020)
This paper presents the methodology for estimation of power delivery and efficiency of the tip-jet helicopter propulsion system. The main advantage of the tip-jet helicopter is the absence of heavy transmission and tail ...
Exposure model for European seismic risk assessment
(Sage Publications Inc, Thousand Oaks, 2020)
Building exposure and vulnerability models for seismic risk assessment have been the focus of a number of European projects in recent years, but there has never been a concerted effort among the research community to produce ...
Risk assessment of oil drilling rig welded pipe based on structural integrity and life estimation
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
Risk assessment procedure based on structural integrity and life estimation has been introduced and applied to oil drilling rig welded pipe. The new concept based on application of structural integrity and life estimation ...
Economic Implications of Innovative Visual Guidance System for Crane Cabins
(Springer, 2020)
This paper proposes innovation through implementation of a real-time computer-aided visual guidance system (VGS) which prevents crane accidents, caused by crane operator’s obstructed view, which can be the cause of collisions ...
Determination of the optimal production plan by using fuzzy AHP and fuzzy linear programming
(IOS Press, Amsterdam, 2020)
In this paper, we consider the problem of determining the optimal production quantity under uncertainties. The treated problem has a critical effect on the achievement of business goals, which further propagates to the ...
Thermomechanical behavior of bio-fiber composite thermal insulation panels
(Elsevier Science Sa, Lausanne, 2020)
The thermomechanical properties of the bio-fiber composite, as material for the production of thermal insulation panels, were evaluated. The observed mixtures were composed of Miscanthus x giganteus bio-fibers, mineral ...
Effect of laser shock peening with and without protective coating on the microstructure and mechanical properties of Ti-alloy
(Elsevier Sci Ltd, Oxford, 2020)
Owing to their good mechanical properties, titanium based alloys are used for machine parts and devices that operate in demanding regimes and environmental conditions. Laser shock peening (LSP) is an innovative technique ...
XFEM based analysis of fatigue crack growth in damaged wing-uselage attachment lug
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
The research presented in this paper is based on the use of extended finite element method (XFEM) for stress intensity factors (SIFs) determination in the case of fatigue crack presented in the wing-fuselage attachment lug ...
