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…

Effects of Buckling on Stress and Strain in Thin Randomly Disordered Tension-Loaded Sheets
Bjorn Skjetne, Torbjorn Helle, Alex Hansen
We study how crack buckling affects stress and strain in a thin sheet with random disorder. The sheet is modeled as an elastic lattice of beams where each of the beams have individ…

Stochastic Model for the Interaction of Buckling and Fracture in Thin Tension-Loaded Sheets
Bjorn Skjetne, Torbjorn Helle, Alex Hansen
We introduce a model of fracture which includes the out-of-plane degrees of freedom necessary to describe buckling in a thin-sheet material. The model is a regular square lattice o…
