High pressure properties of metal using various equations of state

Ram Sharan Singh



We have studied some high pressure properties of metals using various equation of state. The calculation have been performed using modified Rydberg EOS (equation of state), Hama Suito EOS, Stacey Reciprocal K-prime EOS, Kushwah logarithmic EOS, Kushwah Exponential EOS to find the pressure, bulk modulus and its pressure derivative for four metals at different values of compression V/V0 .The results for various parameters show systematic variations with the increase in pressure and compare well with the Stacey EOS.
