Analysis of SA 387 Gr. 91 welded joints crack resistance under static and impact load
(Elsevier Science Bv, Amsterdam, 2021)
This paper presents the results of experimental testing of crack resistance of specimens taken from a welded plate made of steel SA-387 Gr. 91, while taking into account different filler materials and welding procedures ...
Welded joints as critical regions in pressure vessels - case study of vinyl-chloride monomer storage tank
(Savez hemijskih inženjera, Beograd, 2018)
Welded joints are analysed as critical regions in a pressure vessel in respect to structural failure due to the elastic-plastic fracture/crack growth. To assess structural integrity of pressure vessels used in chemical ...
Influence of temperature and exploitation time on hardness and micro-structure of a welded joint in a reactor mantle
(Elsevier Science Bv, Amsterdam, 2018)
This paper presents the analysis of the influence of temperature and exploitation time on the cross-sectional hardness and microstructure changes of characteristic zones of a welded joint made of low-alloyed Cr-Mo steel ...
Impact of temperature and exploitation time on plane strain fracture toughness, k-ic, in a welded joint
(Institut za ispitivanje materijala, Beograd, 2017)
This paper presents the analysis of the impact of temperature and exploitation time on the tendency toward brittle fracture of welded joint constituents of new and exploited low-alloyed Cr-Mo steel A-387 Gr. B, by using ...
Influence of temperature on fracture toughness values in different regions of A-387 Gr. B welded joint
(Elsevier Science Bv, Amsterdam, 2019)
The influence of temperature on fracture toughness values in different regions of a welded joint is analysed low-alloyed Cr-Mo steel A-387 Gr. B, designed for high temperature applications. Heterogeneity of microstructure ...
Experimental determining of fracture behaviour of P460NL1 steel welded joint specimens
(Elsevier Science Bv, Amsterdam, 2019)
This paper is focused on the experimental measuring of impact energy as a part of the doctoral dissertation involving the fatigue behaviour of welded joints, made of fine grain normalised micro-alloyed low carbon high ...
Crack initiation and propagation resistance of hsla steel welded joint constituents
(Institut za ispitivanje materijala, Beograd, 2020)
The welded joint is heterogeneous in its microstructure, mechanical and geometrical properties, thus the stress field is affected by different factors as well as by residual stress. Therefore, special procedures are needed ...
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 ...
The Effect of Material Heterogeneity and Temperature on Impact Toughness and Fracture Resistance of SA-387 Gr. 91 Welded Joints
(MDPI, Basel, 2022)
This paper presents the analysis of the behavior of welded joints made of 9-12% Cr-Mo steel SA-387 Gr. 91. The successful application of this steel depends not only on the base metal's (BM) properties but even more on ...
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 ...
