Dual Phase Austempered Ductile Iron - The Material Revolution and Its Engineering Applications
(Springer International Publishing Ag, Cham, 2020)
During the last few years, there has been an increased interest in improving the strength of ductile iron by means of heat-treating to obtain dual phase microstructures that enhance the properties found in the Austempered ...
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 ...
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 ...
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. ...
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 ...
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 ...
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 ...
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 ...
