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.

多孔样品的冲击压缩数据分析

摘要

关于多种金属（铜，锡，铅，铋，铁和镍）的致密和多孔样品的冲击压缩的文献数据，以及这些数据在嵌入式原子模型（EAM）中的粒子间电势计算中的使用。考虑过的。致密金属的Hugoniot冲击绝热材料为EAM势的计算提供了信息，但是随着初始样品的孔隙率增加，由于与致密样品上获得的数据不一致，它们变得不适用于此目的。考虑了这种不一致的可能原因。
