Tehnologija zavarivanja polimetilmetakrilata (PMMA) / Polymethylmethacrylate (PMMA) welding technology
(DUZS - Društvo za unapređivanje zavarivanja u Srbiji, Beograd, 2010)
Polimetilmetakrilat (PMMA), zbog svojih karakteristika, pre svega transparentnosti i relativno male gustine, predstavlja danas vrlo atraktivan materijal u inženjerstvu. Zbog toga, istražuju se nove mogućnosti spajanja ovog ...
Predviđanje veka čeličnog žičanog užeta u eksploataciji / Service life prediction of running steel wire ropes
(Institut za ispitivanje materijala, Beograd, 2010)
Vrlo visoka čvrstoća omogućava žičanom užetu da prenese velike zatezne sile i da se kreće po koturima relativno malog prečnika. Žice od čelika vrlo visoke čvrstoće su postojale više od sto godina pre nego što su patentirane, ...
Analiza loma spojnice lanca / Failure analysis of chain bracket
(Integritet i vek konstrukcija, Beograd, 2011)
