Impact of temperature and exploitation time on plane strain fracture toughness, k-ic, in a welded joint
(Institut za ispitivanje materijala, Beograd, 2017)
This paper presents the analysis of the impact of temperature and exploitation time on the tendency toward brittle fracture of welded joint constituents of new and exploited low-alloyed Cr-Mo steel A-387 Gr. B, by using ...
Simulation of fatigue crack growth in a2024-t351 t-welded joint
(Institut za ispitivanje materijala, Beograd, 2017)
Fatigue crack growth in friction stir welded T joints under three point bending is simulated numerically using the Extended Finite Element Method (XFEM). Three point bending fatigue load stress is applied at the centre of ...
Numerical analysis of stress and strain state of structural elements of container terminal
(Institut za ispitivanje materijala, Beograd, 2017)
The results of the research regarding the stress and strain state in structural elements of the container terminal are presented in this paper. The container terminal is used for the electrical energy supply and control ...
Expectations, reality and perspectives in using bim for the green building design
(Institut za ispitivanje materijala, Beograd, 2017)
In the late 1970s when the first programs for building energy consumption simulation appeared, architectural practice was based on paper documentation and 2D drafting programs were considered as state of the art technologies. ...
Cracking due to repair welding of the treiber roll
(Institut za ispitivanje materijala, Beograd, 2017)
Repair welding has caused crack initiation in the upper Treiber roll in the steel works plant mill at Zelezara in Smederevo. The upper and lower Treiber rolls serve the purpose of folding and directing rolled metal strips, ...
Design and manufacture of reformer in polymer electrolyte membrane fuel cell
(Institut za ispitivanje materijala, Beograd, 2017)
The paper describes the development and manufacturing aspects of the reformer in polymer electrolyte membrane (PEM) fuel cell, from the first step of realization that includes modelling the main parts of the reformer; ...
Izvijanje cilindrične tankozide strukture izrađene od legure aluminijuma sa greškom u geometriji u vidu udubljenja, pod dejstvom aksijalnog pritiska / Buckling behaviour of dented aluminium alloy cylindrical shell subjected to uniform axial compression
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2017)
Tankozide cilindrične strukture imaju veoma visoku primenu u industriji. Pošto su obično opterećene na aksijalni pritisak, najčešći uzrok njihovog otkaza je pojava izvijanja. U ovom članku se prikazuje numerička analiza ...
Istraživanje geometrijskih karakteristika pravozubih konusnih zupčanika sa malim uglom gornjeg konusa bez ozubljenog većeg a sa ozubljenim manjim zupčanikom / Research on geometrical characteristics of straight bevel gears with a small shaft angle with a non-generated gear and generated pinion
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2017)
Korišćenjem konusnih zupčanika sa malim uglom precesije gornjeg konusa razvijen je pogon za jedan deo opreme na gas i ulje. Zupčanici se odlikuju visokim stepenom iskorišćenosti (oko 0,9) i malim početnim obrtnim momentom. ...
Wear resistance improvement of thermal plant fan mill impact plates based on numerical flow simulation
(Institut za ispitivanje materijala, Beograd, 2017)
Numerical simulation of 3D multiphase flow is performed to determine the velocity field in the fan mill. The mixture model of the Euler-Euler approach is used. Recirculating gas is a primary phase that carries granular ...
Fatigue life estimation of cct specimen using xfem
(Institut za ispitivanje materijala, Beograd, 2017)
In this study a central crack tension (CCT) specimen is chosen for analysis to demonstrate the capability and reliability of the extended finite element method (XFEM) in predicting the crack propagation trajectory and ...
