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 ...
Osnove ispitivanja integriteta šipova s primerima iz prakse / Basis of pile integrity testing with few case histories
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2012)
U poslednjih nekoliko godina, ispitivanje integriteta ugrađenih šipova postalo je veoma popularno na gradilištima u našoj zemlji. Pri tom, posebno mesto zauzima zvučna metoda, 'Sonic Integrity Test' kao pouzdana, jeftina ...
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 ...
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 ...
Metodologija reparaturnog zavarivanja vratila turbina na hidroelektrani Đerdap 2 bez demontaže agregata
(Institut IMK "14. oktobar", Kruševac, 2012)
Na deset hidro-generatorskih jedinica 'Đerdap 2' ugrađene su horizontalne Kaplan turbine, nominalne snage 28 MW, izrađene u Rusiji. Posle 163411h rada (približno 22 godine) došlo je do loma vratila turbine agregata A6 u ...
Monte Carlo Analysis of the Influence of Different Packaging on MOSFET Energy Response to X-rays and Gamma Radiation
