Curenje posude za skladištenje CO2 od austenitnog čelika / Leakage of an austenitic steel CO2 storage tank
(Institut za ispitivanje materijala, Beograd, 2012)
Posle pojave vodenih kapi na spoljašnjem zidu otvora za reviziju posude za skladištenje ugljen dioksida, detaljnom inspekcijom je otkrivena mreža prslina na prirubnici revizionog otvora, blizu zavarenog spoja između ...
Integrity and Life Assessment Procedure for a Reactor
(Elsevier Science Bv, Amsterdam, 2019)
Integrity and life assessment of structural elements or structures subjected to variable loads is necessary in order to define the control interval and removal of damages that occurred during exploitation. Integrity and ...
Risk based analysis of temperature and time effects on brittle fracture of A-387 Gr. B welded joint
(Elsevier Science Bv, Amsterdam, 2019)
Risk based analysis of temperature and time effects on fracture toughness values is applied to different regions of a welded joint made of low-alloyed Cr-Mo steel A-387 Gr. B, designed for high temperature applications. ...
Numerical prediction of ductile fracture resistance of welded joint zones
(Elsevier Science Bv, Amsterdam, 2016)
This study deals with the numerical prediction of ductile fracture initiation and development in welded joints of a high strength low alloyed steel. Having in mind the material heterogeneity in the joint zone, a combined ...
Relation between impact and fracture toughness of A-387 Gr. B welded joint
(Elsevier Science Bv, Amsterdam, 2019)
The influence of temperature on impact and fracture toughness values in different regions of a welded joint is analysed for low-alloyed Cr-Mo steel A-387 Gr. B, designed for high temperature applications. Standard Charpy ...
Compatibility of fracture mechanics parameters and fatigue crack growth parameters in welded joint behaviour evaluation
(Strojarski Facultet, 2013)
Problem of fracture toughness, K-Ic, determination on a crack tip localized in a welded joint is set in principle, since fracture mechanics presumes homogeneous material, not only in a crack tip surrounding but on a distance ...
Strategija održavanja zasnovana na riziku - primenljivost na cevovod / Applicability of risk-based maintenance strategy to a penstock
(Institut za ispitivanje materijala, Beograd, 2012)
Rizik od krtog loma cevovoda reverzibilne turbine je ocenjen u ranoj fazi projektovanja. Da bi se smanjili troškovi izgradnje cevovoda prihvaćen je jedan tunel. Zbog toga je za najopterećeniji segment cevovoda izabran HSLA ...
Scenario razvoja loma u rotorskom bageru / Scenario of fracture development in bucket wheel excavator
(Institut za ispitivanje materijala, Beograd, 2013)
Produženi rad rotorskog bagera (BWE) u teškim radnim uslovima može dovesti do otkaza mašina. Kod veoma važnih elemenata konstrukcije, može dovesti do katastrofalnog loma. Lociranje važnih elemenata konstrukcije je od ...
Integrity and life assessment of welded joints made of micro-alloyed high strength steels
(Trans Tech Publications Ltd., 2020)
Structural integrity and life of welded joints made of a micro-alloyed low-carbon fine-grained normalised high strength pressure vessel steel, P460NL1 is presented [1]. The research performed within the scope of this topic ...
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 ...
