Application of neural networks in determination of compressive strength of concrete
(Revista Romana de Materiale/ Romanian Journal of Materials, 2012)
This paper presents the optimization of concrete mixtures composition related to a physical property and the process of production of trial mix design by using the multi-layered feed-forward neural networks. This optimization ...
Spregnuti nelinearni problemi u analizi konačnim elementima - studija slučaja / Coupled nonlinear problems in finite element analysis: A case study
(Integritet i vek konstrukcija, Beograd, 2012)
Rad daje opis analize elastoplastičnih deformacija čeličnog cevnog apsorbera kinetičke energije sudara železničkih vozila metodom konačnih elemenata (FEM). Eksperimentalna istraživanja korišćena su kao osnova za modeliranje ...
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 ...
Failure analysis of hydraulic turbine shaft
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
This paper describes the analysis of major failure of 28 MW horizontal hydro turbine shaft. The analysis of load carrying capacity of critical radius and fractography analysis are presented. Special emphasize is on ...
Methodology of determination the influence of corrosion pit on decrease of hydro turbine shaft fatigue life
(Univerzitet u Novom Sadu - Fakultet tehničkih nauka, Novi Sad, 2012)
This paper describes the influence of corrosion on stress concentration factor and crack initiation at shaft flange transition section. The case study of hydraulic turbine shaft failure is used as the basis for this research. ...
Građevinski materijali na bazi elektrofilterskog pepela kao rešenje za smanjenje zagađenja vazduha prouzrokovano emisijom iz termoelektrana / Building materials based on fly ash as possible solution for reduction of air pollution caused by emissions from power-plants
(Savez inženjera i tehničara Srbije, Beograd, 2012)
Najčešći uzročnici zagađenja životne sredine su emisije uzrokovane različitim tehnološkim procesima koji se odvijaju u termoelektranama. Velika produkcija elektrofilterskog pepela, koji je glavni ostatak pri sagorevanju ...
The possibility of substitution of wear resistant low chromium white iron resistant with basalt melt
(Editura Stiintifica Fmr, Bucharest, 2012)
In this study the testing results of the possibility of substituting mill lining plates for ore milling made of low chromium white iron that is resistant to wear with plates made of basalt melt are presented. Plates made ...
MSV sistem za obradu signala sa neutron-gama diskriminacijom u mešovitom polju / MSV signal processing system for neutron-gamma discrimination in a mixed field
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2012)
Na osnovu principa koji su proizišli iz Kempbelove teoreme, u ovom radu je urađena analiza nekih mogućnosti Kempbelovog MSV sistema za obradu signala. MSV mod je posebno pogodan za merenja koja se sprovode u mešovitom polju ...
Evalution of concretes with standard and recycled raw materials for high temperature application
(Revista Romana de Materiale/ Romanian Journal of Materials, 2012)
Concrete undergoing thermal treatment before and during life-service can be applied as building material for thermal insulation in high-temperature plants. When such concretes are designed with secondary raw materials they ...
Analiza stabilnosti vitkog 3D modela šipa u interakciji sa tlom metodom konačnih elemenata
(Društvo za integritet i vek konstrukcija SrbijeInstitut IMS, 2012)
The paper describes the modelling and stability analysis of slender piles using finite element method. The concept of a modified stability analysis of 3D model pile–soil–pile cap is formulated; it is formed from solid ...
