Pressure dependence of the thermal conductivity of insulators
TLDR
In this paper, the effects of pressure, both hydrostatic and uniaxial, on the thermal conductivity of insulators are evaluated in the high-temperature range, assuming a constant relaxation time.Abstract:
The effects of pressure, both hydrostatic and uniaxial, on the thermal conductivity of insulators are evaluated The calculation is carried out in the high-temperature range, assuming a constant relaxation time Comparison of the calculated results for hydrostatic pressure with the available experimental data shows reasonable agreement The effect of uniaxial compression is found to be somewhat smaller than that of hydrostatic pressureread more

TL;DR: In this paper, the variation of the thermal conductivity of single-crystal NaCl under uniaxial compression was investigated by the dynamic hot-strip method, and no effect whatsoever was found.

Thermo-elastic plane deformations in doubly-connected domains with temperature and pressure which depend of the thermal conductivity
TL;DR: In this paper, a weak formulation for the plane problem of thermoelastic theory in multiply-connected domains is proposed to avoid the difficulties connected with the Cesaro-Volterra boundary conditions in the related elliptic boundary-value problem.

GRÜNEISEN PARAMETER OF NaCl AT HIGH COMPRESSIONS
TL;DR: In this paper, a new method of determining the pressure dependence of the Gruneisen parameter was described, which was carried out on NaCl to 33 kbar at room temperature using an end-loaded pistoncylinder apparatus.
