The static indentation fracture mechanics approach does not fully capture the rate sensitive nature of failure behavior in ceramics. Accordingly, a dynamic indentation technique was developed to investigate material removal mechanisms at strain rates similar to those encountered in realistic grinding situations. The technique is designed to deliver a single indentation load of duration 100 microseconds. Compared to static loading, it is observed that lateral cracking is promoted under dynamic loading rates. The implications of dynamic loading on the material removal mechanisms are discussed.
