  • A new method for calculating cold energy, cold pressure and cohesive energy was poroposed. Cohesive energy calculations for 52 metals show that the calculated results using this method are consistent with the experimental data, especially for alkali metals. Comparison of Hugoniot curves calculated based on cold energy and cold pressure with the experimental Hugoniot data of aluminum, copper, zinc and silver, shows that this method can be applied to calculate cold energy and cold pressure of solid materials.
