Effect of material heterogeneity and constraint conditions on ductile fracture resistance of welded joint zones - Micromechanical assessment
(Pergamon-Elsevier Science Ltd, Oxford, 2017)
The topic of this work is assessment of ductile fracture initiation and development in different zones of welded joint of a high strength low alloyed (HSLA) steel. A combined experimental-numerical procedure is applied for ...
Modelling of ductile crack growth in welded joints using micromechanical failure criterion
(17th European Conference on Fracture 2008: Multilevel Approach to Fracture of Materials, Components, 2008)
In this paper, ductile crack growth in strength mismatched welded joints is considered. High-strength low-alloyed (HSLA) steel in quenched and tempered condition is used as the base metal. Two different fillers are selected ...
Micromechanical analysis of constraint effect on fracture initiation in strength mismatched welded joints
(Trans Tech Publications Ltd, 2007)
In this paper the micromechanical approach to ductile fracture was applied in a study of constraint effect on crack growth initiation in mismatched welded joints. The single-edged notched bend specimens (precrack length a ...
Micromechanical analysis of mechanical heterogeneity effect on the ductile tearing of weldments
(Elsevier Sci Ltd, Oxford, 2012)
The objective of this study is determination of the effect of mechanical heterogeneity on ductile crack initiation and propagation in weldments using micromechanical approach. Welded single-edge notched bend (SENB) specimens ...
Fracture assessment of seam and seamless steel pipes by application of the ring-shaped bending specimens
(Elsevier, Amsterdam, 2019)
The topic of this work is analysis of fracture behaviour and resistance of the thin-walled seamless and seam steel pipes, through application of the recently proposed ring-shaped specimen (PRNB - Pipe Ring Notched Bend). ...
Ductile fracture resistance of the weld metal and heat affected zone in a HSLA steel welded joint
(European Conference on Fracture, ECF, 2012)
Ductile damage development in welded joints of high strength low alloyed (HSLA) steel NIOMOL 490K was examined experimentally and analyzed using the micromechanical approach. Single-edge notched bend (SENB) specimens, cut ...
Ductile fracture of pipe-ring notched bend specimens - Micromechanical analysis
(Pergamon-Elsevier Science Ltd, Oxford, 2017)
Integrity of pipes is typically assessed by testing fracture mechanics specimens, such as compact tensile (CT) or single-edge notched bending (SENB). However, for some pipe dimensions it is not easy or possible to fabricate ...
Local approach to analysis of ductile fracture in welded joints-Influence factors
(18th European Conference on Fracture: Fracture of Materials and Structures from Micro to Macro Scale, 2010)
Local approach is applied to analysis of ductile fracture in steel welded joints. Welded single-edge notched bend (SENBspecimens with joints containing one or two weld metals are investigated. The Gurson plastic flow ...
Application of Complete Gurson Model for prediction of ductile fracture in welded steel joints
(Trans Tech Publications Ltd, 2009)
Ductile fracture process includes three stages: void nucleation, their growth and coalescence. The voids nucleate due to the fracture or separation of non-metallic inclusions and secondary-phase particles from the material ...
