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 ...
An overview of application of micromechanical models in ductile fracture analysis of welded joints
(Srpsko društvo za mehaniku, Beograd, 2020)
Fracture of welded joints has been an important research and industrial topic for a long time, having in mind the key role of welded joints in ensuring the safe operation and integrity of welded structures. This work ...
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 ...
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 ...
An experimental verification of numerical models for the fracture and fatigue of welded structures
(Institute of Metals and Technology, 2007)
By allowing a more detailed analysis, numerical modelling has an important role to play in the development of structures. However, the results of a numerical model's analysis have to be verified with an experimental analysis ...
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 ...
Procena čvrstoće zavarenih spojeva na tankim cilindričnim ljuskama oslabljenim aksijalnom prslinom, modifikovanom rei metodom
(Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije (SMEITS), Beograd, 2002)
U radu su analizirani modifikovana REI metoda i mogućnost njene primene na zavarene spojeve tankih cilindričnih ljuski, ne uzimajući u obzir specifičnost zavarenih spojeva (heterogenost strukture, zaostale napone i ...
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 ...
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 ...
