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 ...
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 ...
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: ...
Micromechanical coupled study of crack growth initiation criterion in pressure vessel steel
(Strength of Materials, 2004)
We present results of the combined design-theoretical investigation of the mechanism of crack growth at the onset of ductile fracture of NPP reactor pressure vessels. Micromechanical approach to the prediction of ductile ...
Case study of supporting tubes failure
(Kluwer Academic Publishers, 2006)
Fracture toughness of alloyed austempered ductile iron (ADI)
(Kluwer Academic Publishers, 2006)
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 ...
Effects of structure characteristics on mechanical properties of aluminum alloy matrix composites
(Trans Tech Publications Ltd, 2004)
Composite materials based on the CW67 alloy (Al base matrix) and volume fraction of 15 pet of SiC particles in two nominal sizes (0.7 μm and 33 μm) have been produced by hot pressing. The fracture behavior of the composite ...
