Numerical Simulation of Fatigue Crack Growth in Titanium Alloy Orthopaedic Plates
(Univ Osijek, Tech Fac, Slavonski Brod, 2020)
Biomaterials intended for orthopaedic plates manufacturing have much higher mechanical properties relative to the bone itself and still there are many cases where those plates fracture in service, with fatigue as the main ...
Crack initiation and propagation resistance of hsla steel welded joint constituents
(Institut za ispitivanje materijala, Beograd, 2020)
The welded joint is heterogeneous in its microstructure, mechanical and geometrical properties, thus the stress field is affected by different factors as well as by residual stress. Therefore, special procedures are needed ...
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Experimental investigation of the integrity of casing pipes, used in the oil drilling rigs, withdrawn after about 70,000 h of service, has been conducted, together with numerical simulation.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 ...
The largest pre-stressed concrete Dome in the world - the case study of "Hall 1 of the Belgrade Fair"
(Elsevier, Amsterdam, 2020)
The aim of the paper is to present the largest pre-stressed concrete free-standing structure in the world the Dome of the "Hall 1 of the Belgrade Fair", designed by Academician Branko ZeZelj, prominent Serbian scientist, ...
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 ...
Design Aspects of Hip Implant Made of Ti-6Al-4V Extra Low Interstitials Alloy
(Elsevier Science Bv, Amsterdam, 2020)
The main concerns in design of hip implants are fracture and fatigue related issues. In this paper, reverse engineering is used to redesign a hip implant produced by precision casting, using Ti6Al4V Extra Low Interstitials ...
Extended FEM analysis of fatigue crack growth in Ti-6Al-4V orthopaedic plates
(Elsevier, Amsterdam, 2020)
The extended finite element method (xFEM) was used to analyse fatigue crack growth in orthopaedic locking compression plates (LCP), made of Titanium alloy, Ti-6Al-4V, loaded in four-point bending. The optimal geometry was ...
Analytical vs Numerical Calculation of Fatigue Life for Different Welded Joint Regions
(Univ Osijek, Tech Fac, Slavonski Brod, 2020)
This research will show the analytical way of determining the remaining life of a welded joint with a fatigue crack initiated in its heat affected zone. The calculation will be divided into two stages, since the fatigue ...
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 ...
