Summary

A number of new experimental techniques were developed to simplify the process of calibrating ceramic constitutive models. Current ceramic model calibration techniques for the Johnson-Holmquist One (JH1) model require the use of complicated penetration experiments to tune the damage evolution to a specific experiment Application of these ceramic models to different experiments often illustrates discrepancies in the results.

This paper will illustrate the use of data from these new experimental methods to simplify the calibration process for hot-pressed silicon carbide (SiC), and thus more accurately capture the behavior of different ceramic materials. Dynamic sphere impacts as well as kinetic energy rod penetration rate study programs have been established. Comparison of the experimental data with the corresponding simulation results will highlight areas for improvement in ceramic modeling. Specifically, the macroscopic behavior the constitutive model attempts to encompass and its relation to relevant static and dynamic properties.
