Hyperballistic superdiffusion and explosive solutions to the non-linear diffusion equation
Eirik G. Flekkøy, Alex Hansen, Beatrice Baldelli
By means of a particle model that includes interactions only via the local particle concentration, we show that hyperballistic diffusion may result. This is done by findng the exac…
Crack Localization and the Interplay between Stress Enhancement and Thermal Noise
Santanu Sinha, Subhadeep Roy, Alex Hansen
We study the competition between thermal fluctuations and stress enhancement in the failure process of a disordered system by using a local load sharing fiber bundle model. The the…
The Three Extreme Value Distributions: An Introductory Review
Alex Hansen
The statistical distribution of the largest value drawn from a sample of a given size has only three possible shapes: it is either a Weibull, a Fréchet or a Gumbel extreme value di…
Fatigue and failure of a polymer chain under tension
Harish Charan, Alex Hansen, H. G. E. Hentschel +1
The rupture of a polymer chain maintained at temperature under fixed tension is prototypical to a wide array of systems failing under constant external strain and random pertur…
Phase transitions and correlations in fracture processes where disorder and stress compete
Santanu Sinha, Subhadeep Roy, Alex Hansen
We study the effect of the competition between disorder and stress enhancement in fracture processes using the local load sharing fiber bundle model, a model that hovers on the bor…
Onsager-Symmetry Obeyed in Athermal Mesoscopic Systems: Two-Phase Flow in Porous Media
Mathias Winkler, Magnus Aa. Gjennestad, Dick Bedeaux +3
We compute the fluid flow time-correlation functions of incompressible, immiscible two-phase flow in porous media using a 2D network model. Given a properly chosen representative e…
