Acoustic emission AE waveforms were recorded during compression of the ceramic Alumina AD995. The frequency contents of the wave form were determined using FFT technique. It was found that signals which represented damagecrack growth had frequencies between 39 and 80 kHz. Experiments were also performed on post-shocked AD995 specimens. Significant differences were observed which demonstrated that AE technique could be used for damage evolution determination.
