Fracture Roughness and Correlation Length in the Central Force Model
Jan Øystein Haavig Bakke, Thomas Ramstad, Alex Hansen
We measure the roughness exponent and the correlation length exponent of a stress-weighted percolation process in the central force model in 2D. The roughness exponent is found to…

Mean Field Theory of Localization in the Fuse Model
Renaud Toussaint, Alex Hansen
We propose a mean field theory for the localization of damage in a quasistatic fuse model on a cylinder. Depending on the quenched disorder distribution of the fuse thresholds, we…
