Numeričko modelovanje otvaranja vrha prsline u zavarenom spoju / Numerical modeling of crack tip opening in welded joint
(Institut za ispitivanje materijala, Beograd, 2010)
Zavareni spoj je heterogene strukture sa područjima različitih mikrostruktura. Da bi ispitali lokalno ponašanje područja prateći otvaranje prsline, problem je postaviti vrh zareza u željeni položaj. Izvedena je simulacija ...
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 ...
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. ...
Determination of Residual Fatigue Life of Welded Structures at Bucket-Wheel Excavators through the Use of Fracture Mechanics
(Elsevier Science Bv, Amsterdam, 2018)
This paper presents a methodological approach for the assessment of service life of vital welded structures of a bucket-wheel excavator Sch Rs 650/5x24 ('Thyssen Krupp', Germany) boom, subjected to cyclic loading with a ...
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 ...
Repair Welding Of Lower Rails Of A 30CrMoV9 Steel Transport Beam And The Conditions Under Which The Welding Procedure Must Be Carried Out
(Proceedings of the 5th International Scientific Conference on Advances in Mechanical Engineering (ISCAME 2017), 2017)
Welding technology used for repairing of the lower rail of a 30CrMoV9 steel transport beam is
presented in this paper. Following the previously performed repair welding, a large number of
cracks were detected, located ...
The influence of the temperature and exploitation time on the behaviour of a welded joint subjected to variable and impact load
(International Conference on New Trends in Fatigue and Fracture, 2018)
This paper presents the analysis of the temperature and exploitation time influence on the resistant measure to brittle fracture of welded joint constituents of the new and exploited low-alloyed Cr-Mo steel A-387 Gr. B ...
Analysis of the Influence of Microstructure Heterogeneity and Mechanical Properties of Welded Joint Constituents on Fracture Toughness for Plane Strain, K-Ic
(Trans Tech Publications Ltd, Durnten-Zurich, 2012)
The problem of fracture toughness, K-Ic, determination at a crack tip localized in a welded joint is placed in principle because fracture mechanics assumes homogenous material, not only around the crack tip but on a distance ...
