Otpornost prema habanju i lomu reparaturno navarenih točkova kranskih dizalica / Wear and failure resistance of repair surface welded crane wheels
(Univerzitet u Beogradu, Mašinski fakultet, 2016)
Osnovni predmet ove disertacije je da se korišćenjem njenih rezultata omogući odvijanje proizvodnog procesa sa minimalnim troškovima održavanja uz minimalno učešće živog rada, što je inače svakodnevni zadatak savremene ...
Structural dynamic modification of a tubular collector
(Proceedings of the 5th International Congress of Serbian Society of Mechanics, 2015)
Dynamic modification of structures involves the transformation of an existing model in the
new one, which has better behavior and higher accuracy in comparison with the existing. The
main objective of a dynamic modification ...
Temperature fields and residual stresses in welded joints of high-strength steel / Temperaturska polja i zaostali naponi u zavarenim spojevima čelika povišene čvrstoće
(Univerzitet u Beogradu, Mašinski fakultet, 2014)
The effect of the residual stresses and strains is one of the most important parameters in the structural integrity assessment. A finite element model is constructed in order to simulate the multi passes mismatched submerged ...
Analysis of the stress field in a model of pipe branches
(Proceedings of TEAM 2015, 7th International Scientific and Expert Conference of the International TEAM Society, 2015)
The aim of this paper is to analyze the stress field of
a complex geometry model of pipe branches loaded
with internal pressure of 10 bar. The analysis will be
done by comparing method of strain gauges and a
new one ...
Micromechanical fracture analysis of high strength steel weldments / Mikromehanička analiza loma zavarenih spojeva čelika povišene čvrstoće
(Univerzitet u Beogradu, Mašinski fakultet, 2013)
The industrial application of high strength steel in structural welded components has increased the demand for understanding the ductile failure behavior of this type of welded materials. Therefore, integrity assessment ...
Determination of internal pressure value causing pipe branch model to plastically deform
(International Conference of Experimental and Numerical Investigations and New Technologies, 2017)
Complexity of pressure vessels geometry usually causes stress and strain concentrations. Modern approach of stress and strain analysis involves numerical and experimental testing. Every experimental testing on the construction ...
