AE counts-AE energy-stress-time curves under different loading rates: (a) AE counts-stress-time curves when the loading rate is 5 × 10−7 m/s; (b) AE energy-stress-time curves when the loading rate is 5 × 10−7 m/s; (c) AE counts-stress-time curves when the loading rate is 5 × 10−6 m/s; (d) AE energy-stress-time curves when the loading rate is 5 × 10−6 m/s; (e) AE counts-stress-time curves when the loading rate is 1.7 × 10−5 m/s; (f) AE energy-stress-time curves when the loading rate is 1.7 × 10−5 m/s; (g) AE counts-stress-time curves when the loading rate is 5 × 10−5 m/s; (h) AE energy-stress-time curves when the loading rate is 5 × 10−5 m/s.
