Constitutive Relations in Second Sound Thermo-Electroelasticity

Here we present some results of paper [1], which contains the thermodynamic restrictions on the constitutive relations for an electrically polarizable and finitely deformable heat conducting elastic continuum interacting with the electric field. The constitutive equations include an evolution equation for the heat flux; the latter and the temperature obey a frame-invariant form of Cattaneo’s equation. [1] A.
