Procena ponašanja zavarenog spoja HSLA čelika opterećenog na zamor primenom parametara mehanike loma / Assessment of the behaviour of fatigue loaded HSLA steel welded joint by applying fracture mechanics parameters
(Institut za ispitivanje materijala, Beograd, 2012)
U zavarenim spojevima, sa gledišta mehanike loma, se pretpostavlja prisustvo prslina, gde se onda vek s obzirom na zamor takvih konstrukcija sa prslinama procenjuje vremenom rasta prsline pod promenljivim opterećenjem. ...
Recovery of the damages of a welded steel structure of a coal-reloading bridge: Methodological approach
(Univerzitet u Novom Sadu - Fakultet tehničkih nauka, Novi Sad, 2012)
In present paper, the methodological approach to the analysis of the causes of failures and to recovery of the damages has been presented using, as an example, the fracture and damage of a welded steel structure of a ...
Linings based chromite for application in foundry
(ModTech Publishing House, 2012)
In this work, a possibility to develop new chromite-based refractory linings for casting applications has been examined. Lining composition optimization with the controlled reologic properties was achieved by applying ...
Microstructure analysis and crack detection in turbine blades after prolonged exposure in plant
(Univ Novi Sad, Fac Tech Sci, Adeko, Novi Sad, 2012)
Turbine blades are one of the most important machine parts in every power generator. Corrosion and/or erosion attack on blades are also available in moisture atmosphere, because the wet water vapour is an usual working ...
Removal of toxic metals from industrial sludge by fixing in brick structure
(Elsevier Sci Ltd, Oxford, 2012)
The aim of this study was to test utilization possibilities of industrial sludge in masonry industry, as well as risk of toxic elements leaching potential. Sludge is generated in a hot-dip galvanizing process after waste ...
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 ...
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 ...
