Abstract
Three continuum compaction models are calibrated to planar impact data for CeO2 powder and used to predict the shock compaction behavior of CeO2 powder under cylindrically converging shock wave loading. All experiments and computations are performed on powder compacts with an initial pressed density of 4.0 g/cm3 (56% TMD). A magnetically-driven, cylindrically-converging shock compaction experiment is computationally designed using the calibrated compaction models in the multi-physics code FLAG. Magnetohydrodynamic (MHD) calculations of impact conditions are performed using a calibrated circuit model in FLAG. The first cylindrical shock compaction experiment is executed using the mobile pulsed power driver PHELIX. In situ areal density measurements of the CeO2 target assembly are performed during the compaction event with proton radiography. Calculations of the late time compaction response of the CeO2 powder under PHELIX compression are greater than 90% accurate using the P-α compaction models calibrated under planar loading.
