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. ...
Fatigue life assessment of the structure with widespread damage exposed to high temperature
(Elsevier Science Bv, Amsterdam, 2020)
The exhaust nozzle represents a part of a jet engine which is crucial to its overall performance, since it accelerates the flow of hot gases out of the engine and creates a thrust. During its long service, it is exposed ...
Material Effects on Risk Assessment of Residual Life of Oil Drilling Rig Pipe
(Elsevier, Amsterdam, 2020)
Fracture mechanics parameters are used for numerical and analytical risk assessment of residual life of a cracked oil drilling rig welded pipe. Number of cycles to the critical crack length, obtained by direct integration ...
Education management and information and communication technologies
(Association of Economists and Managers of the Balkans, 2021)
The education system is facing the permanent challenge to adapt to the constantly changing
states in science, technology, and economy, and it plays an important role in the overall society development and socio-economic ...
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 ...
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 ...
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 ...
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, ...
