Structural integrity assurance of casing pipes in the oil and gas industry
(WIT Transactions on the Built Environment, 2013)
The exploitation of casing steel pipes used in oil and gas drilling rigs typically involves a corrosive atmosphere, high pressures and elevated temperatures. These conditions can affect the initiation and development of ...
Experimental and numerical cross-correlated modal analysis of the floor structure dynamics in a thermal power plant
(Institut za ispitivanje materijala, Beograd, 2015)
This article presents search methodology after the cause of excessive floor vibrations in a thermal power plant control room. The floor structure is a composition of a steel grillage and concrete slabs at 12 m level above ...
Unapredenje industrijske bezbednosti kranskih kabina / Industrial safety improvement of crane cabins
(Institut za ispitivanje materijala, Beograd, 2015)
Cranes significantly contribute to efficient work progress but also have a great potential to cause large life and financial losses. Cranes today do not meet the needs of large proportion of operators, therefore making ...
Failure prediction of gas and oil drilling rig pipelines with axial defects
(Elsevier Science Bv, Amsterdam, 2014)
Working conditions of casing pipes in drilling rigs can significantly influence the initiation and development of damage in the material, and therefore also the safe service of the entire system. In this work, an integrity ...
Finite element analysis of fracture resistance parameters for stationary semi-elliptical surface cracks in high strength steel
(Institut za ispitivanje materijala, Beograd, 2015)
This study deals with numerical simulations based on elastic-plastic finite element method for nonlinear stress analyses on pre-cracked tensile specimens with high strength properties. The influence of crack geometry on ...
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 ...
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. ...
