Abstract
There is a requirement for off-Hugoniot data to validate material and equation of state models. One technique is to use projectiles with graded shock impedance layers in a gas gun to impact a target and apply a ramp loading. To accurately design a pressure profile to be applied to the target the impactor must be accurately characterised and modelled. Modelling also provides an assessment of whether lateral rarefactions will hinder the experiment, and increases confidence in the analysis of the results obtained. This paper considers several methods for calculating the equation of state of layered mixtures for application to the modelling of graded density impactors.
