Effect of temperature and exploitation time on tensile properties and plain strain fracture toughness, K-Ic, in a welded joint
(Elsevier Science Bv, Amsterdam, 2018)
Effect of temperature and exploitation time on resistance to brittle fracture of welded joint constituents of new and 40 years exploited low-alloyed Cr-Mo steel A-387 Gr. B has been analysed. The plane strain fracture ...
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 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 ...
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 ...
Crack growth resistance of weldment constituents
(Elsevier Science Bv, Amsterdam, 2018)
The ovennatching can affect the occurrence of cold cracks after welding in high-strength low-alloyed steels of 770 MPa yield strength class. The welding consumable has been designed in a way to produce WM with slightly ...
Numerical and Experimental Investigations of Fracture Behaviour of Welded Joints with Multiple Defects
(MDPI, Basel, 2021)
Current standards related to welded joint defects (EN ISO 5817) only consider individual cases (i.e., single defect in a welded joint). The question remains about the behaviour of a welded joint in the simultaneous presence ...
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 ...
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 ...
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 ...
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 ...
