Equations of state of the elastic energy of metals in the case of a nonspherical strain tensor

Interpolation expressions of the equations of state and the coefficient of thermal conductivity are presented for iron (α-phase), aluminum, nickel, lead, and titanium. These expressions constitute a new way of writing the equations of state presented in [1]. The expression for the “cold energy” is interpolated within the compression interval 0.9 ≤ δ ≤ 2.0 in such a way that the cold pressure and the square of the velocity of sound would be polynomials of powers δ-1.
