General Expressions for the Description of the Influence of Stresses on Dielectric Permittivity or Magnetic Permeability

We construct general expressions for the description of the influence of initial stresses on the dielectric permittivity and magnetic permeability of materials capable of taking into account various nonlinear effects and the phenomena of inherent or induced anisotropy. It is shown that the indicated influence is proportional to the tensor modulus of striction of the material and depends on the piezoeffect modulus. However, the last dependence is insignificant if the inverse piezoeffect is comparable with striction.
