Weibull probability distribution for reactor steel 20MnMoNi55 cleavage fracture in transition temperature
(Elsevier, Amsterdam, 2020)
This paper presents the results and methods used for determining of fracture toughness of reactor steel, denoted as 20MnMoNi55, typically used for structures working at low temperatures, in transition temperature area. In ...
Primena Pareto analize u istraživanju bezbednosnih aspekata rada dizalica / Pareto analysis application in research of crane related accidents
(Savez inženjera i tehničara Srbije, Beograd, 2020)
Prethodna istraživanja ukazuju na nedovoljnu istraženost bezbednosnih aspekata rada dizalica. Stoga, prvi cilj ovog istraživanja čine prikupljanje i analiza podataka o akcidentima uzrokovanim radom dizalica, koji su se ...
Stress Analysis of a Pipeline as a Hydropower Plant Structural Element
(Assoc Mechanical Engineers Technicians Slovenia, Ljubljana, 2020)
This paper describes pipeline stress analysis, primarilybranch junctions, as a structural element in hydro-power plants. Pipelines are exposed to internal pressure,which is present under working conditions. Analysis of ...
Mišljenje učenika srednjih škola u Srbiji o prednostima onlajn učenja tokom pandemije Covid-19 / Mnenie učenikov srednih škol v serbii o preimuŝestvah onlajn-obučeniâ vo vremâ pandemii Covid-19
(Pedagoško društvo Srbije, Beograd i Univerzitet u Beogradu - Filozofski fakultet - Institut za pedagogiju i andragogiju, Beograd, 2020)
Poslednjih godina svedoci smo brojnih istraživanja i pilot-projekata, kako kod nas tako i u svetu, koji se bave ispitivanjem onlajn učenja. U radu se teorijski i empirijski analiziraju mogućnosti onlajn učenja. Teorijski ...
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 ...
Experimental and numerical study of temperature field during hard-facing of different carbon steels
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2020)
In this research the 3-D transient non-linear thermal analysis of the hard-facing process was performed by using the experimental testing and finite element method. Testing was done at three different carbon steels and the ...
FEM simulation of welded joint geometry influence on fatigue crack growth resistance
(Elsevier, Amsterdam, 2020)
Fatigue behaviour of welded joints is investigated, in terms of welded joint geometry and the fatigue crack position. It is based on previous work which involved numerical simulation of fatigue crack growth in a welded ...
Rules of Risk Management - Case Study of Open Pit Mine
(Elsevier, Amsterdam, 2020)
The issue of human factor risk and rules and regulations in open pit mine is a main focus of this paper in order to develop predictive models of behavior of workers in relation to compliance with the procedures and rules. ...
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 ...
