In this contribution, a general formulation for constitutive equations of electromechanical active media is presented. Motivated by experimental observations, our approach is based on an additive decomposition of the Helmholtz free energy in elastic and inelastic parts and on a multiplicative decomposition of the deformation gradient in passive and active parts. The derivation is thermodynamically sound and accounts for geometric and material nonlinearities. Exemplarily, we present the solution of a uniaxial electromechanical problem and discuss the evolution of the active deformation.
