Micro Abstract:
This paper presents a variational and computational framework for nonlinear electromechanics based on a new convex multi-variable definition of the internal energy. This ensures: a) the material stability of the governing equations (ellipticity) and b) allows to introduce new multi-field variational principles which open up interesting possibilities in terms of using various interpolation spaces for the different fields, leading to enhanced type formulations.
