Static and dynamic fracture mechanics parameters of material in the heat-affected-zone
(11th International Conference on Fracture 2005, ICF11, 2005)
The behaviour of heat-affected-zone (HAZ) in welded joints of structural steels with different chemical composition and different strength class (yield strength ranged from 450 to 700 MPa) has been evaluated, applying two ...
Finite element modeling of pressure vessel with two internal surface crack
(11th International Conference on Fracture 2005, ICF11, 2005)
This paper deals with the finite element modeling of the pressure vessel with two artificial internal surface cracks, one positioned in the vessel center and the other one close to the vessel cover. Cracks are made by ...
Weldability testing of microalloyed steel and integrity assessment of welded joint
(Institut International de la Soudure, 2005)
The results of weldability assessment of high strength low carbon microalloyed steel are presented. These results are used for integrity assessment of weldments. Two aspects of behaviour were considered. These are the risk ...

Welded penstock, produced of high-strength steel and application of fracture mechanics parameters to structural integrity assessment
(Springer, Dordrecht, 2008)
Application of high-strength steel for welded penstock increased the probability of crack-like defects and in welded joint. Structural integrity assessment procedure is presented and applied to welded penstock produced of ...
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 ...
Fracture mechanics and non-destructive testing for structural integrity assessment
(Trans Tech Publications Ltd, Durnten-Zurich, 2009)
Fracture mechanics parameters can be applied for the analysis of failures of structures, and also for prevention of failures when defects in a structure are detected and defined. The approach is presented through stages: ...
Structural integrity assessment by local approach to fracture
(Kluwer Academic Publishers, 2006)
Evaluation of damage of steam pipeline steel using local approach to fracture
(American Society of Mechanical Engineers, Pressure Vessels and Piping Division (Publication) PVP, 2008)
In the paper, the level of damage of steam pipeline steel after about 100,000 hours at 540°C (1004 °F) under pressure of 42 bars (609 PSI) is analyzed. Material degradation is estimated using a combined experimental and ...
