Influence of crack length on ductile fracture initiation in welded joints with one and two weld metals
(Trans Tech Publications Ltd, Durnten-Zurich, 2011)
Among various micromechanical models for ductile fracture analysis using local approach, those based on the Gurson plastic flow criterion have been intensively developed in the past three decades. However, their application ...
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 ...
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 ...
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 ...
