The simulation of Gugoniot pressures for the Ni and Cu in the electron density functional method

An original method based on the electron density functional method have been used to simulate on the computer the pressure-volume relations $P(V)$, the zero-temperature isotherms and Gugoniot pressures for nickel and copper. For calculating metal's properties under pressure additional parameters are not introduced, but the model functionals for equilibrium are used. In the paper the simulation of the crystal's free energy items are analyzed in detail. This model method allows to calculate isentrope of unloading and equation of state for transition metals.
