Representative volume element approximations in elastoplastic spring networks
Sabine Haberland, Patrick Jaap, Stefan Neukamm +2
We study the large-scale behavior of a small-strain lattice model for a network composed of elastoplastic springs with random material properties. We formulate the model as an evol…

The Parallel Full Approximation Scheme in Space and Time for a Parabolic Finite Element Problem
Oliver Sander, Ruth Schöbel, Robert Speck
The parallel full approximation scheme in space and time (PFASST) is a parallel-in-time integrator that allows to integrate multiple time-steps simultaneously. It has been shown to…
