Failure of Soda-Lime Glass at Extreme Conditions: New Experimental Frontiers
Abstract
Short Statement of Work:~ Discuss needs for normal-impact reference data with ONR-supported team of collaborators working on high-strain-rate properties of soda-lime glass in order to define optimal experimental program.~ Perform standard tests at his unique facility in Caltech~s Lindhurst Lab 40 mm propellant gun, which includes: design, manufacture, and characterize projectile, target, and diagnostic assemblies for a series of about nine (9) experiments on the.~ Execute experiments, measuring (at least) projectile velocity and shock velocity in real time, as well as (optionally) wave arrival profiles, rarefaction overtake times, Hugoniot elastic limits, shock temperatures or post-shock temperatures.~ Interpret data to obtain Hugoniot equation of state, sound speed along Hugoniot, strength profile, multiple wave structures, failure wave characteristics, any phase transitions that occur.~ Repeat above measurements along isentropic compression path instead of Hugoniot. Optionally, carry out customized loading/unloading path experiments to reach specific presssure-temperature-strain conditions.~ Collaborate with dynamic shear experimental group and computational modelers to assimilate data into optimal mechanical model of soda-lime glass under confining pressure at high strain rates.~ Integrate soda-lime glass model with microscopic models of glass and liquid structure and dynamics in general, for both Earth science and mechanical engineering applications.~ In parallel, continue simulation-and-design iteration to find whether cone-impact is a viable alternative to shear-plane impact for characterization of shear strain under pressure.
