API J55 Steel Casing Pipe with an Initial Surface Crack under Internal Pressure - Determination of Fracture Parameters
(Trans Tech Publications Ltd, Durnten-Zurich, 2012)
Seam casing pipe used in an oil drilling rig, manufactured by high frequency (HF) contact welding of API J55 steel, is tested. The influence of an initial defect (machined surface crack) is analysed, by performing pressure ...
Quantification of stress raiser influence on decrease of machine parts fatigue life
(Univ Novi Sad, Fac Tech Sci, Adeko, Novi Sad, 2012)
This paper displays the usage of Theory of Critical Distances (TCD) in the prediction of high-cycle fatigue behaviour in machine parts and systems. It is possible to gain real overview of stresses of machine parts by Finite ...
Prediction of crack initiation in spur gear contact zone
(Univ Novi Sad, Fac Tech Sci, Adeko, Novi Sad, 2012)
The objective of this paper is to give a new viewpoint in contact fatigue prediction in the case of high-cycle fatigue. The presented research is based on up-to-date methods and multidisciplinary approach, and enables ...
Controller area network based monitoring of vehicle's mechatronics system
(SISY 2011 - 9th International Symposium on Intelligent Systems and Informatics, Proceedings, 2011)
The implementation of various electronic subsystems in different kinds of on-road and off-road vehicles is constantly expanding. Accordingly, the new vehicles, instead of being mechanical systems, become advanced mechatronics ...
Elastic-plastic behaviour of welded joints during loading and unloading of pressure vessels
(Elsevier Science Bv, Amsterdam, 2016)
In this paper elastic-plastic behaviour of welded joints during loading and unloading of pressure vessel has been analysed. Two stage pressuring process has been applied in previous experimental investigation and simulated ...

Structural integrity assessment by local approach to fracture
(Kluwer Academic Publishers, 2006)
Welded penstock, produced of high-strength steel and application of fracture mechanics parameters to structural integrity assessment
(Springer, Dordrecht, 2008)
Application of high-strength steel for welded penstock increased the probability of crack-like defects and in welded joint. Structural integrity assessment procedure is presented and applied to welded penstock produced of ...
Evaluation of damage of steam pipeline steel using local approach to fracture
(American Society of Mechanical Engineers, Pressure Vessels and Piping Division (Publication) PVP, 2008)
In the paper, the level of damage of steam pipeline steel after about 100,000 hours at 540°C (1004 °F) under pressure of 42 bars (609 PSI) is analyzed. Material degradation is estimated using a combined experimental and ...
Experimental determination of J-integral at elevated temperatures
(17th European Conference on Fracture 2008: Multilevel Approach to Fracture of Materials, Components, 2008)
In past two decades, the development of 9-12% Cr creep-resistant steel for critical components in coal-fired power stations that can withstand higher temperatures and pressures has been intensified in order to increase ...
