Title: Imaging perturbed shock propagation in powders

Abstract

A novel experimental methodology is presented to study the deviatoric response of powders in shock regimes. The powders are confined to a cylindrical wedge volume, and a projectile-driven shock wave with a sinusoidally varying front propagates through the powder. The perturbed shock wave exhibits a damping behavior due to irreversible processes of viscosity and strength (deviatoric) of the powder with propagation through increasing powder thicknesses. The inclined surface of the wedge is polished and coated to establish a diffuse surface suitable for reflecting incident laser light into a high-speed camera imaging at 5 MHz. Images of the contrast loss upon shock wave arrival at the observation surface are post-processed for qualitative and quantitative information. New data of shock damping behavior with parameters of perturbation wavelength and initial shock strength are presented for powders of copper, tantalum, and tungsten carbide as well as their mixtures. We present the first full-field images showing additional spatial disturbances on the perturbed shock front that appear dependent on particle material and morphology.

Shock wave perturbation decay in granular materials

Journal Article Vogler, Tracy J. - Journal of Dynamic Behavior of Materials

A technique in which the evolution of a perturbation in a shock wave front is monitored as it travels through a sample is applied to granular materials. Although the approach was originally conceived as a way to measure the viscosity of the sample, here it is utilized as a means to probe the deviatoric strength of the material. Initial results for a tungsten carbide powder are presented that demonstrate the approach is viable. Simulations of the experiments using continuum and mesoscale modeling approaches are used to better understand the experiments. The best agreement with the limited experimental data is obtainedmore »« less

Observation of a Kelvin-Helmholtz Instability in a High-Energy-Density Plasma on the Omega Laser

Journal Article Harding, E C ; Hansen, J F ; Hurricane, O A ; ... - Physical Review Letters

A laser initiated experiment is described in which an unstable plasma shear layer is produced by driving a blast wave along a plastic surface with sinusoidal perturbations. In response to the vorticity deposited and the shear flow established by the blast wave, the interface rolls up into large vortices characteristic of the Kelvin-Helmholtz (KH) instability. The experiment used x ray radiography to capture the first well-resolved images of KH vortices in a high-energy-density plasma, and possibly the first images of transonic shocks generated by large-scale structures in a shear layer. The physical processes governing the evolution of a stratified fluidmore »« less

Shock-Driven Hydrodynamic Instability Growth Near Phase Boundaries and Material Property Transitions: Final Report

Technical Report Peralta, Pedro ; Fortin, Elizabeth ; Opie, Saul ; ...

Activities for this grant included: 1) Development of dynamic impact experiments to probe strength and phase transition influence on dynamic deformation, 2) development of modern strength and phase aware simulation capabilities, 3) and post-processing of experimental data with simulation and closed form analytical techniques. Two different dynamic experiments were developed to probe material strengths in solid metals (largely copper and iron in this effort). In the first experiment a flyer plate impacts a flat target with an opposite rippled surface that is partially supported by a weaker window material. Post mortem analysis of the target sample showed a strong andmore »« less

Strength and viscosity effects on perturbed shock front stability in metals

Journal Article Opie, Saul ; Loomis, Eric Nicholas ; Peralta, Pedro ; ... - Physical Review Letters

Computational modeling and experimental measurements on metal samples subject to a laser-driven, ablative Richtmyer-Meshkov instability showed differences between viscosity and strength effects. In particular, numerical and analytical solutions coupled with measurements of fed-thru perturbations; generated by perturbed shock fronts, onto initially flat surfaces show promise as a validation method for deviatoric response in the post shocked material. The analysis shows that measurements of shock perturbation amplitudes at low sample thickness-to-wavelength ratios are not enough to differentiate between strength and viscosity effects, but that surface displacement data of the fed-thru perturbations appears to resolve the ambiguity. Additionally, analytical and numerical resultsmore »« less

Bounds on the Rate-Dependent Plastic Flow of Tantalum up to 75 GPa

Journal Article Reed, B. W. ; Patterson, J. R. ; Nguyen, J. H. ; ... - Journal of Dynamic Behavior of Materials

In this study we report on the continued development of thermodynamics-based analysis of shock waves propagation with the objective of extracting information related to materials strength at high strain rates and pressures. Building on previous results reported for peak stresses of 10 GPa and 25 GPa, we present a series of three-step gas-gun shock experiments designed to explore the pressure and strain rate dependence of plastic flow in polycrystalline tantalum. These experiments at nominal peak stresses of 50 GPa and 75 GPa show the irreversible deformation before pullback to be almost entirely confined to the shock loading, with negligible plasticmore »« less
