Eksperimentalno analiziranje rasta prsline u pojedinim konstituentima zavarennh spojeva kompleksno legirannh čelika visoke čvrstoće na epruvetama i u realnim konstrukcijama, kao i uticaj rasta prsline na sigurnost zavarenog ...
Procena integriteta i veka zavarenog panela primenom lokalnih napona / Assessment of the integrity and life of welded panel using local stresses
(DUZS - Društvo za unapređivanje zavarivanja u Srbiji, Beograd, 2022)
Relevantne lokalne karakteristike zamornog opterećenja su najveći amplitudni napon i odgovrajauća srednja vrednost napona, koje treba odrediti za celu komponentu. Relevantna svojtva materijala se onda upoređuju sa dobijenim ...
Experimental and numerical stress and strain analysis of the boiler reversing chamber tube plate
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2022)
Boilers are one of the most used units for both heat generation plants and industry systems. Their operation is subjected to different working loads and maintenance requirements. Exploitation experience points out critical ...
