description | Penetration experiments with long rods into SiC ceramics are available for two rod materials over a wide range of impact velocities [1-2]. The ceramics used in these experiments were initially intact, without cracks or other induced damage. The penetration response of three types of pre-damaged SiC was also investigated [3]. The pre-damaged targets, which were confined in 7075 aluminum sleeves consisted of 1) thermally shocked (many non-contiguous cracks), 2) thermally shocked with mechanical load/unload cycling (in-situ comminuted), and 3) compacted powder. Further experiments were conducted on intact and thermally shocked (predamaged) SiC-N that overlapped the previous test data, and to extend the data to lower impact velocities. The results of these additional experiments were different than expected; this article describes the experiments and comparisons with previous data.
