Local dynamics of a randomly pinned crack front: A numerical study
Knut Skogstrand Gjerden, Arne Stormo, Alex Hansen
We investigate numerically the dynamics of crack propagation along a weak plane using a model consisting of fibers connecting a soft and a hard clamp. This bottom-up model has prev…
Making the case of GPUs in courses on computational physics
Knut Skogstrand Gjerden
Most relatively modern desktop or even laptop computers contain a graphics card useful for more than showing colors on a screen. In this paper, we make a case for why you should le…
Universality Classes in Constrained Crack Growth
Knut S. Gjerden, Arne Stormo, Alex Hansen
Based on an extension of the fiber bundle model we investigate numerically the motion of the crack front through a weak plane separating a soft and an infinitely stiff block. We fi…
A model for stable interfacial crack growth
Knut Skogstrand Gjerden, Arne Stormo, Alex Hansen
We present a model for stable crack growth in a constrained geometry. The morphology of such cracks show scaling properties consistent with self affinity. Recent experiments show t…
Onset of Localization in Heterogeneous Interfacial Failure
Arne Stormo, Knut Skogstrand Gjerden, Alex Hansen
We study numerically the failure of an interface joining two elastic materials under load using a fiber bundle model connected to an elastic half space. We find that the breakdown…
Model for Density Waves in Gravity-Driven Granular Flow in Narrow Pipes
Simen Å. Ellingsen, Knut S. Gjerden, Morten Grøva +1
A gravity-driven flow of grains through a narrow pipe in vacuum is studied by means of a one-dimensional model with two coefficients of restitution. Numerical simulations show clea…
