A modified soda-lime glass model for shock physics simulations from elastic response to ~100 GPa

Recent high-pressure shock data on soda-lime glass (SLG) has been collected and added to the existing database for this material. This comprehensive dataset characterizing the shock response of SLG from elastic conditions through 120 GPa was aggregated and evaluated. Guided by key observations, particularly from the high-pressure data, a modified glass model equation of state (EOS) was developed and implemented within the CTH hydrocode. The details of this modified formulation and its parameterization for SLG are presented. Improved model capabilities are demonstrated through correlation to time-resolved measurements from plate impact tests spanning the full stress range. Additional interpretation of experimental results with tandem model calculations offers new insights into the complexities of SLG under shock compression.
