Abstract:

The extreme compression value of the pressure derivative of bulk modulus i.e. Koo has been treated as an adjustable parameter in recent studies on high pressure equations of state (EOS) for solids. The present study presents the elastic behaviour of metals i.e. Iron, Aluminium and Copper under high compression with  the help of Birch-Murnaghan, Bre-Stacey, Shanker, Born, Vinet, Bardeen, Ullaman and Tait Equations of state.

Further these EOS have been critically examined by evaluating the values of pressure derivative of bulk modulus at infinite pressure. The value of this parameter is found out to be grater than 5/3 by some EOS in case of Fe, Al and Cu such results is in good agreement with the Seismic Study of these metals.
