Microstructure and fracture of alloyed austempered ductile iron
(Elsevier Science Inc, New York, 2006)
An investigation has been conducted on two austempered ductile irons alloyed with Cu and Cu+Ni, austenitized at 900 degrees C and austempered at 350 degrees C. The microstructure and fracture mode developed through these ...
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 ...

The invention relates to a fin for heat exchangers with at
least one louver arrangement in the region between associ-
ated tubes for the heat transfer from one medium to another
medium. The louver arrangement is provided ...
An Approach to the Optimization of a Thin-walled Z-beam
(Strojniski Vestnik/Journal of Mechanical Engineering, 2009)
One approach to the optimization of a thin-walled open section Z-beam subjected to bending and to the constrained torsion is considered. For given loads, material and geometrical characteristics the problem is reduced to ...
Micromechanical analysis of constraint effect on fracture initiation in strength mismatched welded
(Trans Tech Publications Ltd, Durnten-Zurich, 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 ...
