Numerička analiza loma zatezne epruvete sa prslinom u ZUT / Numerical analysis of tensile specimen fracture with crack in HAZ
(Kluwer Academic Publishers, 2006)
Numeričkim rešenjima se omogućava istraživanje složenijih problema, uključujući analizu pojedinačnih uticaja, posebno u slučajevima kada izostaju odgovarajući eksperimenti i matematička rešenja usled visoke cene, složenosti ...
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 ...
Analiza oštećenja i naponskog stanja poluga mlinova za ugalj termoelektrane na fosilna goriva / Damage and stress state analysis of fossil fuel power plant coal mill crank
(Visoka tehnička škola strukovnih studija, Beograd, 2006)
U radu je dat prikaz oštećenja koja se javljaju kod poluga mlinova za ugalj termoenergetskih postrojenja u uslovima eksploatacije. Nastala oštećenja mogu da budu takvog karaktera da poluge mlinova za ugalj izgube svoju ...
An experimental verification of numerical models for the fracture and fatigue of welded structures
(Institute of Metals and Technology, 2007)
By allowing a more detailed analysis, numerical modelling has an important role to play in the development of structures. However, the results of a numerical model's analysis have to be verified with an experimental analysis ...
The effect of annealing temperatures and cooling rates on microstructure and mechanical properties of investment cast Ti-6Al-4V alloy
(Elsevier Sci Ltd, Oxford, 2006)
Production of investment castings of titanium alloys was considerably increased during last years due to the significant cost savings compared to complicated machined parts. However, the disadvantage of as-cast titanium ...
Structural integrity assessment by local approach to fracture
(Kluwer Academic Publishers, 2006)
Modelling of ductile fracture initiation in strength mismatched welded joint
(Pergamon-Elsevier Science Ltd, Oxford, 2008)
In this paper, the effect of strength mismatch and width of the welded joints oil the stress-strain distribution in the crack tip region has been discussed. The single-edge notched bend (SENB) specimens (precrack length ...
Radiation Absorption Characteristics of Titanium Alloys
(Polish Acad Sciences Inst Physics, Warsaw, 2009)
Titanium alloys have found numerous applications in space research, and nuclear industry and research. Since X-rays constitute an important part of the space radiation environment, numerical simulations of radiation ...
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 ...
Termohidraulika isparivača ložišta parnog kotla sa prinudnom cirkulacijom / Thermal-hydraulics of evaporating tubes in the forced circulation loop of a steam boiler
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2008)
Elektroprivreda Srbije je u toku 2005. godine nastavila radove na izgradnji TE Kolubara B snage 350 MW, koji su započeti još davne 1989. godine. Sam kotao je toranjske konstrukcije, a za isparivač kotla predviđeno je ...
