3-D model of solid and gas phase flow in the duct bend behind the mill gas classifier at the fan mill
(Nis University, 2011)
This paper shows the computer simulation of two-phase flow of the mill gases, the solid particles of monodisperse coal dust and the transport fluid. Numeric simulation was performed with the software pack Fluent 6.3.26, ...
Experimental analysis of fatigue fracture behaviour of Ti-6Al-4V alloys
(Scientific Society for Mechanical Engineering, 2011)
Static and dynamic fracture mechanics parameters of material in the heat-affected-zone
(11th International Conference on Fracture 2005, ICF11, 2005)
The behaviour of heat-affected-zone (HAZ) in welded joints of structural steels with different chemical composition and different strength class (yield strength ranged from 450 to 700 MPa) has been evaluated, applying two ...
Welded penstock, produced of high-strength steel and application of fracture mechanics parameters to structural integrity assessment
(Springer, Dordrecht, 2008)
Application of high-strength steel for welded penstock increased the probability of crack-like defects and in welded joint. Structural integrity assessment procedure is presented and applied to welded penstock produced of ...
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 ...
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 ...
Modelling of ductile crack growth in welded joints using micromechanical failure criterion
(17th European Conference on Fracture 2008: Multilevel Approach to Fracture of Materials, Components, 2008)
In this paper, ductile crack growth in strength mismatched welded joints is considered. High-strength low-alloyed (HSLA) steel in quenched and tempered condition is used as the base metal. Two different fillers are selected ...
Analysis of loading steel structure of bucket wheel excavator by stress condition measuring
(Institute of Mechanical Engineering, 2009)
Micromechanical analysis of constraint effect on fracture initiation in strength mismatched welded joints
(Trans Tech Publications Ltd, 2007)
In this paper the micromechanical approach to ductile fracture was applied in a study of constraint effect on crack growth initiation in mismatched welded joints. The single-edged notched bend specimens (precrack length a ...
