Experimental and numerical study of globe valve housing
(Savez hemijskih inženjera, Beograd, 2017)
Complex structure experimental analysis has always been a huge challenge for researchers. Conventional experimental methods (e.g., strain gauges) give only limited data sets regarding measurement on critical areas with ...
Structural integrity analysis of a cracked pressure vessel
(Institut za ispitivanje materijala, Beograd, 2021)
Stress distribution, as obtained by finite element method (FEM), and corresponding fracture mechanics parameters, have been used for the integrity assessment of a pressure vessel. Once the stress distribution is known, the ...
Numerical and experimental strength analysis of fire-tube boiler construction
(Faculty of Mechanical Engineering in Slavonski Brod, Faculty of Electrical Engineering in Osijek, Faculty of Civil Engineering in Osijek, 2011)
Norms, such as EN 12952-3 and EN 12953-3 handle the issues concerned with calculation of the pressurized boiler components, not however considering the influences of thermal strains that are often of vital importance for ...
Numerical analysis of constraint effect on ductile tearing in strength mismatched welded cct specimens using micromechanical approach
(Faculty of Mechanical Engineering in Slavonski Brod, Faculty of Electrical Engineering in Osijek, Faculty of Civil Engineering in Osijek, 2011)
In this paper, constraint effect on ductile fracture initiation and propagation has been studied. Three-dimensional finite element analyses of mismatched welded joints made of high strength steel, have been performed for ...
Raspodela napona kao uzrok otkaza korenog dela industrijskog čeličnog dimnjaka / Stress distribution as a cause of industrial steel chimney root section failure
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2008)
Ovaj rad razmatra iniciranje otkaza korene sekcije industrijskog čeličnog dimnjaka visine 60 m. Prsline nastale u čeličnoj strukturi spoljašnjeg plašta dimnjaka značajno su uticale na integritet strukture. Izvršena je ...
A new methodology for prediction of high-cycle contact fatigue for spur gears
(Univerzitet u Novom Sadu - Fakultet tehničkih nauka, Novi Sad, 2012)
High-cycle contact fatigue is a localized phenomenon that occurs in highly stressed grains of the material on or under the contact region. The contact zones of tooth flanks for meshed gears are subjected to contact fatigue ...
Analiza stabilnosti vitkog 3D modela šipa u interakciji sa tlom metodom konačnih elemenata / Buckling analysis of 3D model of slender pile in interaction with soil using finite element method
(Institut za ispitivanje materijala, Beograd, 2012)
U radu je prikazano modeliranje i analiza rezultata stabilnosti vitkih šipova primenom metode konačnih elemenata. Formulisan je koncept za modifikovanu analizu stabilnosti 3D modela šip-naglavna ploča-tlo formiran od solid ...
Modeliranje uticaja matrične poroznosti na elastične osobine poroznih biokompozita / Modeling of the matrix porosity influence on the elastic properties of particulate biocomposites
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2012)
Porozni materijali se koriste za široki spektar inženjerskih struktura napravljenih na bazi keramike, poroznih legura sa memorijskim efektom, penastih struktura, termički zaštitnih filmova. U skorije vreme primena poroznih ...
