Formation of shear bands through discrete localized plastic increments
Heiner Olbermann, Hidde Schönberger
We study rate-independent systems in which the evolution is obtained by incremental minimization of elastic energy and one-homogeneous dissipation under constraints on the admissib…
Interacting phase fields yielding phase separation on surfaces
Benjamin Lledos, Roberta Marziani, Heiner Olbermann
In the present article we study diffuse interface models for two-phase biomembranes. We will do so by starting off with a diffuse interface model on defined by two c…
Connecting disclinations by ridges
Peter Gladbach, Heiner Olbermann
We consider a thin elastic sheet with a finite number of disclinations in a variational framework in the Föppl-von Kármán approximation. Under the non-physical assumption that the…
Phase separation on varying surfaces and convergence of diffuse interface approximations
Heiner Olbermann, Matthias Röger
In this paper we consider phase separations on (generalized) hypersurfaces in Euclidian space. We consider a diffuse surface area (line tension) energy of Modica-Mortola type and p…
Consistent and convergent discretizations of Helfrich-type energies on general meshes
Vincent Degrooff, Peter Gladbach, Heiner Olbermann
We show that integral curvature energies on surfaces of the type have discrete versions for triangular complexes, where t…
Godunov variables and convex entropy for relativistic fluid dynamics with bulk viscosity
Heiner Olbermann
Based on the conservation-dissipation formalism proposed by Zhu and collaborators we formulate a general version of the Israel-Stewart theory for relativistic fluid dynamics with b…
