Hydrogen embrittlement of low carbon structural steel
(Elsevier Science Bv, Amsterdam, 2014)
Hydrogen embrittlement (HE) of steels is extremely interesting topic in many industrial applications, while a predictive physical model still does not exist. A number of studies carried out in the world are unambiguous ...
Material characterization of the main steam gate valve made of X20CrMoV 12.1 steel after long term service
(Elsevier Science Bv, Amsterdam, 2014)
Martensitic steel X20CrMo12.1 has been extensively used within the last few decades as a material for tubing systems and pipelines in thermal power plants (TPP). Long term behavior of this steel is very well known and ...
Numerical modelling of crack propagation in friction stir welded joint made of aluminium alloy
(Elsevier Science Bv, Amsterdam, 2014)
In this work, fatigue crack propagation in thin-walled aluminium alloy structure with two friction stir welded (FSW) joints has been numerically modelled. Crack propagation in unstiffened part of the structure between two ...
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 ...
Numerical modeling of austenite-ferrite weldment tensile test
(Elsevier Science Bv, Amsterdam, 2014)
The aim of this paper was to numerically simulate the plastic behavior of a three-material body specimen and compare the results with physical experiments performed on the same specimen. Both the physical and numerical ...
