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 ...
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 ...
Stress intensity factors numerical calculations for two penny shaped cracks in the elastic solid
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
In the face of enormous costs of developing new aircraft, high fuel prices, increasingly demanding environmental standards, harsh economic race and the fight against competing manufacturers, today's aviation is adapting ...
Human factor risk management procedures applied in the case of open pit mine
(Pergamon-Elsevier Science Ltd, Oxford, 2021)
Risk management aims to provide a controlled work environment to ensure the safe operation of the high-risk systems. It is a dynamic process which work in a continual state of change. The issue of human factor risk and ...
Experimental and numerical analysis of stress-strain field of the modelled boiler element
(Springer, 2021)
Hot water boilers are most commonly used devices in thermal and industrial plants for heat production. Boilers elements are exposed to high pressures and temperatures during boiler operation. Non-stationary working regimes ...
Development and Improvement of Numerical Models of Welded Joints with Multiple Defects
(Trans Tech Publications, 2023)
This paper presents the development of numerical models which were used to simulate
the behaviour of welded joints containing different combinations of multiple defects under tensile
loads. Four representative combinations ...
Numerical simulation of titanium alloy hip replacement implants behaviour under static and dynamic loads
(HEMIJSKA INDUSTRIJA (Chemical Industry), 2023)
This paper presents development of numerical models for simulation of the behaviour of titanium alloy hip implants under static and dynamic loads, which is a part of extensive research involving the structural integrity ...
Finite element and fracture mechanics analysis of a cracked oil-storage tank
(Društvo za integritet i vek konstrukcija „Prof. dr Stojan Sedmak“, 2023)
Stress distribution, as obtained by the finite element method (FEM), and corresponding fracture mechanics parameters, have been used to assess integrity of a pressure vessel. Once the stress distribution is known, the most ...
Numerical Analysis Of Stress Distribution In Neck Area On Co Cr Alloy Total Hip Replacement Implant
(International Conference of Experimental and Numerical Investigations and New Technologies“ CNN TECH 2017, 2017)
Total hip replacement implants represent permanent implants, and require large bone and cartilage removal during implantation. Revision would affect joint capability to sustain load, which makes this procedure irreversible. ...
Numerical simulation of crack growth in a welded joint with defects
(Elsevier B.V., 2021)
Research presented in this paper involves the numerical simulation of crack growth in a welded joint made of common structural steel S235JR2, but with the presence of a number of different welding defects, which represents ...
