Performance and advanced characterization of shock recovery experiments on soda-lime glassProposal Abstract: Performance and advanced characterization of shock recovery experiments on soda-lime glass Use of soda-lime glass as a component of improved penetration#NAME?" and deformation. As a complement to real-time study of dynamic compression by in situ experiments and simulations, we will carry ou"t recovery of shocked material and detailed characterization of the recovered products.ONR is in possession of a number of powders from recovery experiments already executed in other labs. We will supplement these with 8 new carefully-designed and targeted recov"ery experiments in our lab, using isotopically-enriched starting glass suitable for high-resolution nuclear magnetic resonance chara""cterization.Both the existing and new samples will be studied by optical and electron microscopy, optical and X-ray Raman spectros""copy, X-ray diffraction, and NMR spectroscopy in order to characterize, at multiple scales from atomic-level upwards, the changes in" structure and ordering after shock and recovery. The suite of analyses targets both bulk properties and element-selectivepropertie"s and can be adapted to determine the local environment around O, Na, Al, Si, and Caatoms.The project work is laid out over two y""ears, expected to include about eight new experiments and four trips to the Advanced Photon Source. The particular choice of pressur""es, loading/unloading paths and diagnostic configurations will be selected in consultation with the consortium of researchers studyi"ng high-pressure rheology of soda-lime glass for ONR penetration-resistance studies. The project involves collaboration with an inte"rnational partner in Korea, Prof. Sung-Keun Lee of Seoul National University.
