Crossover behavior in failure avalanches
Srutarshi Pradhan, Alex Hansen, Per C. Hemmer
Composite materials, with statistically distributed threshold for breakdown of individual elements, are considered. During the failure process of such materials under external stre…
Scaling Laws of Stress and Strain in Brittle Fracture
Bjorn Skjetne, Torbjorn Helle, Alex Hansen
A numerical realization of an elastic beam lattice is used to obtain scaling exponents relevant to the extent of damage within the controlled, catastrophic and total regimes of mod…
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…
Brittle Crack Roughness in Three-Dimensional Beam Lattices
Bjorn Skjetne, Torbjorn Helle, Alex Hansen
The roughness exponent is reported in numerical simulations with a three-dimensional elastic beam lattice. Two different types of disorder have been used to generate the breaking t…
