Ponašanje pri zamoru i lomu zavarenih spojeva čelika NIOMOL 490K / Fracture and fatigue behavior of NIOMOL 490K welded joint
(Institut za ispitivanje materijala, Beograd, 2008)
Cilj rada je ispitivanje epruveta radi analize ponašanja prslina u zavarenim spojevima posuda pod pritiskom izrađenim od mikrolegiranog čelika, primenom parametara mehanike loma. Čelik NIOMOL 490K je namenjen za izradu ...
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 ...
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 ...
Procena integriteta zavarene konstrukcije oblika ploče sa prslinom / Structural integrity assessment of welded plate with a crack
(Institut za ispitivanje materijala, Beograd, 2004)
Analiziran je uticaj geometrije (položaj prsline, dimenzije i oblik zavarenog spoja, dimenzija uzorka) i heterogenosti materijala na ponašanje i ocenu integriteta zavarenih ploča. Eksperimentalnom analizom obuhvaćene su ...
Numerical analysis of thermal stresses in welded joint made of steels x20 and x22
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
Stress calculation of steam pipeline is presented, focused on the welded joint. Numerical calculation was peiformed using the finite element method to obtain stress distribution in the welded joint made while replacing the ...
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 ...
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 ...
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 ...
