Abstract : The report examines the sensitivity of material response calculations to the choice of equation of state model. Three equation of state models, all of which are available as subroutines in the RIP code, are considered: (1) modified PUFF; (2) RIP mixed phase; and (3) GRAY. Each of these models is used to calculate the onedimensional response of aluminum, beryllium and titanium; this series of calculations is performed for two distinct xray sources. The sensitivity of the calculated material response to the choice of equation of state model is characterized in terms of the generated impulse and the peak propagating stress at the time the radiation source is cut off. For the calculations presented in this report, the three equation of state models are in fairly good agreement.
