Kumari and Dass[1][2] presented a model based on a linear bulk modulus equation, in the spirit of the Murnaghan equation of state. The equation of state does not correctly model the bulk modulus as the pressure, , tends towards infinity, as it remains bounded. This is apparent in the equation relating the bulk modulus to pressure:

where is the isothermal bulk modulus, is the pressure derivative of the bulk modulus and is a softening parameter for the bulk modulus. This leads to a equation for pressure dependent on these parameters of the form:
