Equation of states at extreme compression ranges: Pressure and bulk modulus as an example

Abstract

This work uses number of theoretical EOSs at extreme compression ranges and it will present a clear picture of extreme compression behavior of materials. This theory has been developed under extreme compressions ranging from 0.01 to 0.001. From theoretical analysis, it has been proved that Pressure and bulk modulus have a special relationship at extreme compressions. To prove this, we have used three different EOSs: the Birch–Murnaghan EOS, the Brennan–Stacey EOS, and the modified Lenard-Jones EOS.
