Abstract: Calculated shock-wave compressed properties of metal platinum is presented based on i)the accurate calculations of 0-K total energies with the self-consistent,relativistic,full-potential,and spin-polarized,linearized augmented plane wave method within the local density approximation to exchenge-correlational functional;and ii)the classical mean-field statistics.The calculations of 0-K total energies span a wide fcc lattice constant range of from 6.1 a.u. to 9.9 a.u.Our approach does not invoke any empirical parameters.The experimental Hugoniot is reproduced excellently.

Key words: Hugoniot state, EOS, LAPW, platinum
