Abstract :
A strongly coupled finite-element formulation of electromechanical interactions in deformable solids is described. The variational form is constructed in a thermodynamically consistent way by using Gibbs´ free energy and differential forms in the material (Lagrangian) domain. The formulation correctly incorporates geometric nonlinearities
