The dynamic response of alumina under shock compression was studied using planar impact experiments with different tile thicknesses. Results show steady spreading of the inelastic shock profile with increasing tile width. Further analysis indicates an expected change in failure mechanism in pressures of about twice the Hugoniot Elastic Limit (HEL). HEL decay phenomenon in alumina is probably a measurement artifact, resulting from the relatively slow response times of manganin gauges.

    In an earlier study on unconfined alumina bar-on-bar impact measured velocity history (using VISAR) data at an impact velocity of 100 m/s showed that the material response is elastic. At higher impact velocities of 220 m/s and 300 m/s, the data suggested the material behavior is inelastic. This...

    The variation of shear strength with impact stress in an alumina-filled epoxy has been measured with lateral stress gauges. At lower stresses, a degree of hardening behind the shock front has been observed, which diminishes as shock stress increases. It is believed that this is due to a...

    The response of polycrystalline alumina to shock is not well addressed. There are several operating mechanisms that only hypothesized which results in models which are empirical. A similar state of affairs in reactive flow modelling led to the development of mesoscale representations of the flow...
