Projekat

Istraživanje i optimizacija tehnoloških i funkcionalnih performansi ventilacionog mlina termoelektrane Kostolac B (MPNTR - 34028)
Primena savremenih mernih i proračunskih tehnika za izučavanje strujnih parametara ventilacionih sistema na modelu energetski izuzetno efikasnog (pasivnog) objekta (MPNTR - 35046)

Sažetak

U radu su prikazani rezultati dobijeni simultanim ispitivanjem čeličnih uzoraka i zavarenih spojeva standardnim metodama i termografijom. Glavni cilj istraživanja je bio da se povežu temperaturne promene uzorka, snimljene termografijom, sa parametrima dijagrama napon - izduženje. Dobijeni rezultati su pokazali da temperaturne promene na površini uzorka, snimljene termografijom, omogućavaju da se predvidi kritični napon i da se definiše kriterijum maksimalno dozvoljene temperaturne promene tokom elastičnih i elastoplastičnih naprezanja, što je veoma značajno za karakterizaciju materijala, dijagnostiku i monitoring složenih metalnih konstrukcija sa zavarenim spojevima.
