Sažetak
U radu su prikazani rezultati dobijeni istovremenim ispitivanjem čelične epruvete DX55D termografijom i standardnim metodama ispitivanja mehaničkih karakteristika materijala. Osnovni cilj ispitivanja je bio da se povežu promene temperature na površini epruvete, kontinuirano registrovani termografskim zapisom, sa dijagramom silaistezanje. Ovo bi omogućilo procenu kritičnih naprezanja koji dovode do loma. Takođe omogućava definisanje kriterijuma za maksimalno dozvoljene temperaturne promene, koje pokazuju da je epruveta izložena elastičnim i elastoplastičnim deformacijama.
