Shearing Resistance of Glasses at High Pressures and High Strain Rates
Abstract
Pressure-Shear Plate Impact (PSPI) experiments are proposed to measure the high-rate shearing resistance of soda-lime glasses at pressures up to approximately 75 GPa at shearing rates of approximately . Experiments will be conducted over a range of pressures that spans the compaction transition in soda-lime glass. To do so, a single stage gas gun will be used at Brown to impose pressures up to 30 GPa. At Cal Tech a powder gun will be used to impose pressures from 20 GPa to 75 GPa. Experimental results will provide a quasi-isentrope for soda-lime glass and its shearing resistance over the full range of pressures attained. The same suite of Pressure-Shear Plate Impact (PSPI) experiments will be conducted at both Brown and Cal Tech, except the impact velocities will be higher at Cal Tech. Experimental data will be shared with modelers. A modest modeling effort will be part of the proposed work in order to facilitate interpretation of experimental results
