Abstract.
We investigate problems in magnetoelasticity, including the
Dzyaloshinskii-Moriya interaction. In the large-strain regime, the
model features a mixed Eulerian-Lagrangian formulation: while
deformations are defined on the reference configuration (Lagrangian),
magnetizations are defined on the deformed set (Eulerian), which is a
priori unknown. This setting leads to various mathematical
difficulties that require an in-depth study of fine and invertibility
properties of admissible deformations to be overcome. First, we
discuss the existence of minimizers of the energy in the static case;
then, we address the existence of energetic solutions driven by the
energy and a rate-independent dissipation. This is joint work with
Elisa Davoli (TU Wien) and Martin Kruzík (Czech Academy of Science).
