Abstract

The literature data on shock compression of compact and porous samples of a number of metals (copper, tin, lead, bismuth, iron, and nickel) and the use of these data in calculations of interparticle potentials in the embedded atom model (EAM) were considered. The Hugoniot shock adiabats of compact metals provide information for calculations of EAM potentials, but as the porosity of the initial samples increases, they become unsuitable for this purpose because of inconsistency with the data obtained on compact samples. Possible reasons for this inconsistency were considered.
