摘要：
Specimens of granite were exposed to uniaxial compression and impacted by a dropped weight in order to obtain time sequences of acoustic emission signals generated due to micro-cracking. Time resolution in the impact fracturing was 10 ns. Both under compression and impact, the macroscale failure stage was preceded by micro-scale damages accumulation stage. The accumulation stage duration under compression is far much longer than the failure stage, while the situation is opposite in case of failure under impact.
