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 ...
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 ...
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 ...
The influence of buffer layer on the properties of surface welded joint of high-carbon steel
(Institute of Metals and Technology, 2011)
Surface welding with buffer layer is often in use because of its well-known properties of plasticity, or ability to slow crack growth initiated. However, in modern surface welding technologies, buffer layer is rarely used. ...
Measurement of local tensile properties of welded joint using digital image correlation method
(Chemicke Listy, 2012)
M. Milosevic(a), N. Mitrovic(b), R. Jovicic(a), A. Sedmak(b), T. Maneski(b), A. Petrovic(b), and T. Aburuga(b) ((a)Innovation Center of Faculty of Mechanical Engineering, b Faculty of Mechanical Engineering, University of ...
Fatigue properties of a high-strength-steel welded joint
(Institute of Metals and Technology, 2007)
In addition to the strength and toughness properties, the fatigue properties of welded joints are necessary for the design of high-strength steel structures exposed to variable loading. Wohler curves were determined for ...
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 ...
Modelling of ductile fracture initiation in strength mismatched welded joint
(Pergamon-Elsevier Science Ltd, Oxford, 2008)
In this paper, the effect of strength mismatch and width of the welded joints oil the stress-strain distribution in the crack tip region has been discussed. The single-edge notched bend (SENB) specimens (precrack length ...
Procena integriteta posuda pod pritiskom sa greškom u zavarenom spoju / Structural integrity assessment of pressure vessels with defect in welded joints
(Vojnotehnički institut, Beograd, 2007)
U radu su prikazani primeri primene parametara mehanike loma za procenu integriteta posuda pod pritiskom sa prslinom. Primena parametara mehanike loma zavisi od niz podataka, pre svega o ponašanju materijala u prisustvu ...
