Turbulent fracture surfaces: A footprint of damage percolation?
Stephane Vernede, Laurent Ponson, Jean-Philippe Bouchaud
We show that a length scale xi can be extracted from the spatial correlations of the "steep cliffs" that appear on fracture surface. Above xi, the slope amplitudes are uncorrelated…
A mesoscale granular model for the mechanical behavior of alloys during solidification
Stéphane Vernède, Jonathan A. Dantzig, Michel Rappaz
We present a two-dimensional granular model for the mechanical behavior of an ensemble of globular grains, during solidification. The grain structure is produced by a Voronoi tesse…
A simple and efficient model for mesoscale solidification simulation of globular grain structures
Stéphane Vernède, Michel Rappaz
A simple model for the solidification of globular grains in metallic alloys is presented. Based on the Voronoi diagram of the nuclei centers, it accounts for the curvature of the g…
