Modeling Of An Advanced Wedge Test

In this work, the shock-material interface behavior at very oblique angles is examined using shock polar analysis as well as full hydrodynamic simulations for two cases : (1) polymethylpentene driving polymethylmethacrylate and (2) polytetrafluoroethylene driving polymethylmethacrylate while using Mie-Gruneisen equations of state. The hydrodynamic simulations were performed using a ghost fluid methodology which utilizes nominally fifth-order spatial and third-order temporal discretizations. The semi-analytical, steady-state, shock polar analysis and full-time dependent hydrodynamic simulations are compared with experimental images obtained using X-ray phase contrast imaging. These comparisons show great qualitative agreement with slight discrepancies present in the streamline flow deflection angles further away from the shock-material interface point.
