Finite element modelling of creep process - steady state stresses and strains
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
Finite element modelling of steady state creep process has been described. Using an analogy of visco-plastic problem with a described procedure, the finite element method has been used to calculate steady state stresses ...
Ocena integriteta rezervoara sa mikroprslinama u zavarenom spoju / Integrity assessment of tanks with microcracks in welded joints
(Institut za ispitivanje materijala, Beograd, 2013)
Tokom eksploatacije rezervoara za skladištenje tečnog ugljendioksida ukazala se potreba za ugradnjom dva nova priključka u jedno od danaca. Rezervoar je izrađen od mikrolegiranog čelika, a priključci od visokolegiranog ...
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 ...
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. ...
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 ...
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 ...
Repair of cracks detected in cast components of vertical kaplan turbine rotor hub
(Institut za ispitivanje materijala, Beograd, 2019)
During the revitalization of the hydroelectric generating station A4 at the hydro power plant 'Djerdap 1', all of its parts are subjected to non-destructive testing. Cracks are detected in cast part of generator rotor hub, ...
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 ...
The effect of cracks on stress state in crane wheel hard-surface under contact loading
(Univ Osijek, Tech Fac, Slavonski Brod, 2017)
Shown in this paper are the results of microstructure testing of crane wheels, along with the repair welding procedure performed by hard-surfacing. Repair welding involved the application of a welded layer to the crane ...
