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, ...
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 ...
True Stress-strain Curves for HSLA Steel Weldment - Iteration Procedure Based on DIC and FEM
(Elsevier, Amsterdam, 2020)
True stress-strain curves of HSLA steel welded joint regions were estimated by using numerical simulation of strains measured by DIC and special iteration procedure to match the results. Strains were measured at certain ...

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. ...
Crack propagation in 3PB specimen made from welded joint
(Elsevier, Amsterdam, 2020)
Crack propagation in 3PB specimen has been investigated experimentally by using Digital Image Correlation (DIC) technique. For this purpose, specimens were taken from butt welded plates, made of P460NL1 micro-alloyed steel. ...
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 ...
