Numerical simulation of multiscale fault systems with rate- and state-dependent friction
Carsten Gräser, Ralf Kornhuber, Joscha Podlesny
We consider the deformation of a geological structure with non-intersecting faults that can be represented by a layered system of viscoelastic bodies satisfying rate- and state-dep…

Numerical Homogenization of Fractal Interface Problems
Ralf Kornhuber, Joscha Podlesny, Harry Yserentant
We consider the numerical homogenization of a class of fractal elliptic interface problems inspired by related mechanical contact problems from the geosciences. A particular featur…

Fractal homogenization of multiscale interface problems
Martin Heida, Ralf Kornhuber, Joscha Podlesny
Inspired by continuum mechanical contact problems with geological fault networks, we consider elliptic second order differential equations with jump conditions on a sequence of mul…
