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 ...
Ductile fracture resistance of the weld metal and heat affected zone in a HSLA steel welded joint
(European Conference on Fracture, ECF, 2012)
Ductile damage development in welded joints of high strength low alloyed (HSLA) steel NIOMOL 490K was examined experimentally and analyzed using the micromechanical approach. Single-edge notched bend (SENB) specimens, cut ...
Lom konstrukcije strele odlagača rotornog bagera C 700 S usled dinamičkih uticaja / The structure failure of the discharge boom of bucket wheel excavator C 700 S due to dynamic effects
(Institut za ispitivanje materijala, Beograd, 2012)
Tokom operacije, kod rotornog bagera (BWE) se razvilo nepovoljno dinamičko ponašanje, plastična deformacija i lom konstrukcije. Posle sprovedene eksperimentalne/numeričke analize, potvrđeno je rezonantno dinamičko ponašanje ...

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 ...
Numerical analysis of anchored bored piles in fractured rock masses
(ICE Publishing, 2015)
Grdelicka gorge, through which upcoming Motorway E-75 will pass by, is made of very old rock masses, influenced by strong tectonic forces and severe physical, chemical and erosion processes. The oldest and most frequents ...
Mars evelope simulation in a high-performance human centrifuge
(International Astronautical Federation, IAF, 2013)
This paper represents an effort to enhance and contribute to the human exploration of Mars, by simulating phases of the Earth-Mars-Earth flight envelope in a high performance human centrifuge. Humans are the most valuable ...
Determining the condition of material for tension bar bucket wheel excavator operating under dynamic working conditions
(European Conference on Fracture, ECF, 2012)
Since the bucket wheel excavator SRs 1200 had crashed with bucket wheel boom heavily damaged, there was an opportunity to analyze the real structure that was in operation for past 40 years. As there are 4 more SRs 1200 ...
Experimental investigation of porous metal bearings
(Inegi-Inst Engenharia Mecanica E Gestao Industrial, Porto, 2012)
Self lubricated sliding bearings production and investigations are still in great expansion because of their very practical maintenance and very long operating life. This is probably the main reason for their common use ...
