Roughness of Crack Interfaces in Two-Dimensional Beam Lattices
Bjorn Skjetne, Torbjorn Helle, Alex Hansen
The roughness of crack interfaces is reported in quasistatic fracture, using an elastic network of beams with random breaking thresholds. For strong disorders we obtain 0.86(3) for…
Elastic Response of Rough Surfaces in Partial Contact
G. George Batrouni, Alex Hansen, Jean Schmittbuhl
We model numerically the partial normal contact of two elastic rough surfaces with highly correlated asperities. Facing surfaces are unmated and described as self-affine with a Hur…
Bulk Flow Regimes and Fractional Flow in 2D Porous Media by Numerical Simulations
Henning Arendt Knudsen, Eyvind Aker, Alex Hansen
We investigate a two-dimensional network simulator that model the dynamics of two-phase immiscible bulk flow where film flow can be neglected. We present a method for simulating th…
A protein model exhibiting three folding transitions
Audun Bakk, Alex Hansen, Kim Sneppen
We explain the physical basis of a model for small globular proteins with water interactions. The water is supposed to access the protein interior in an "all-or-none" manner during…
Thermodynamical implications of a protein model with water interactions
Audun Bakk, Johan S. Hoye, Alex Hansen +1
We refine a protein model that reproduces fundamental aspects of protein thermodynamics. The model exhibits two transitions, hot and cold unfolding. The number of relevant paramete…
Parametrization of Multiple Pathways in Proteins: Fast Folding versus Tight Transitions
Paul G. Dommersnes, Alex Hansen, Mogens H. Jensen +1
Growing experimental evidence shows that proteins follow one or a few distinct paths when folding. We propose in this paper a procedure to parametrize these observed pathways, and…
