Abstract
The current density in a deformed conductor is assumed to be a function of the electric field and the deformation gradients. The form of the relationship is restricted by invariance under changes in orientation of the physical system. Material symmetries impose further restrictions. The resulting form for isotropic materials is given. Simplifications are obtained in the cases of small deformation and large homogeneous deformation. Generalizations and further applications are pointed out.
