Žilavost i duktilnost zavarenih spojeva čelika visoke čvrstoće / Toughness and ductility of high strength steels welded joints
(Institut za ispitivanje materijala, Beograd, 2008)
Tri metode ispitivanja različitim brzinama opterećenja epruveta sa zarezom (udarno klatno, padajući teg, izbočavanje eksplozijom) su primenjene za ocenu žilavosti i duktilnosti ručno elektrolučno zavarivanih spojeva. Osnovne ...
Static and impact crack properties of a high-strength steel welded joint
(Elsevier Sci Ltd, Oxford, 2007)
in order to gain the benefits of weldable high-strength steels in pressurized equipment applications, satisfactory toughness and crack properties of the welded joint, both in the weld metal and the heat-affected-zone (HAZ), ...
Hronologija gubitka integriteta konstrukcija zbog grešaka izrade zavarenih konstrukcija / Chronology of lost structural integrity initiated from manufacturing defects in welded structures
(Institut za ispitivanje materijala, Beograd, 2009)
U različitim vremenskim periodima dolazilo je do gubitka integriteta zavarenih konstrukcija zbog razvoja proizvodnih grešaka zavarenog spoja. Mehanizmi otkaza su bili različiti i uvek su predstavljali novo iskustvo, koje ...

Application of Paris' Law Under Variable Loading
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2022)
The most important characteristics for service safety of welded joints are those describing crack initiation and growth caused by variable loading. Crack initiation and growth caused by variable loading is the subject of ...
Analiza stanja i ocena integriteta kotlova / Analysis of state and integrity assessment of boilers
(Institut za ispitivanje materijala, Beograd, 2005)
Prevremeni otkaz kotlovskih postrojenja može biti izazvan istovremenim uticajem većeg broja tehnološko-metalurških, konstrukcijskih i eksploatacijskih faktora. Zato se povoljna konstrukcijska rešenja, koja obezbeđuju ...
Uticaj prsline na karakteristike zavarenog spoja pri različitim vrstama opterećenja / Influence of crack on welded joint characteristics in different types of loads
(Vojnotehnički institut, Beograd, 2018)
Primena čelika visoke čvrstoće kod projektovanja zavarenih konstrukcija zahteva podatke o svojstvima istih pri različitim uslovima opterećenja. Zahvaljujući visokom naponu tečenja debljina zida može se smanjiti u poređenju ...
Effect of welded joint imperfection on the integrity of pipe elbows subjected to internal pressure
(Faculty of Mechanical Engineering in Slavonski Brod, Faculty of Electrical Engineering in Osijek, Faculty of Civil Engineering in Osijek, 2013)
Since local defects reduce the load-carrying capacity and deformation ability of a piping system, an analysis is undertaken to quantify the influence of weld defects on integrity of the pipe elbows subjected to internal ...
Influence of Temperature on Impact Toughness of HSLA Steels
