Control of a human centrifuge
(University of Belgrade, 2012)
Modeling of welded steel X20 and X22
(University of Belgrade, 2012)
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 ...
Damaged welded pipes for oil and gas rigs exposed to internal pressure - Failure estimation
(European Conference on Fracture, ECF, 2012)
The paper deals with the integrity assessment of API J55 steel casing pipes for drilling rigs, manufactured by high frequency contact welding procedure. The influence of corrosion defects on the pipeline load carrying ...
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 ...
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 ...
Experimental reanalysis of a construction of rotary excavator
(Inegi-Inst Engenharia Mecanica E Gestao Industrial, Porto, 2012)
The diagnostics of construction strength represents the basis for sanation and reconstruction of equipment. It encompasses the analysis of states, behaviours and compliance of the construction, as well as estimation of ...
Značaj i primenljivost ocene integriteta konstrukcija / Significance and applicability of structural integrity assessment
(Institut za ispitivanje materijala, Beograd, 2012)
Da bi se izbegli neočekivani i često ozbiljni otkazi u radu objekata i opreme i sačuvao integritet konstrukcija potrebne su odgovarajuće eksperimentalne i teorijske analize, podržane modeliranjem i numeričkom analizom. ...
