An energy-momentum tensor of the Eshelby type is constructed in the exact theory of nonlinear electrodeformable dielectrics. This tensor does not involve the Maxwell stress of free electric fields. In the quasi-linear approximation the material force defined from this tensor leads to the notion of a path-independent J-integral useful in the study of cracks in electrodeformable ceramics.
