Knowing the compression strength of advanced ceramics at high strain rates is of interest for many applications. The most common method of obtaining a dynamic compression strength value is the split-Hopkinson pressure bar (SHPB) method. Unfortunately a standard test methodology with a standard specimen geometry does not exist for ceramic materials. This leads to questions about data consistency and validity. A three laboratory round robin exercise was conducted to assess the strength of a commercial alumina using the SHPB method and a dumbbell-shaped specimen. These results will highlight the various SHPB parameters used by each round robin participant, determine if the dumbbell-shaped specimen is the appropriate geometry for testing ceramics and show if a consensus strength value was achieved. It will also highlight any issues encountered and propose potential solutions.
