Effects of Particle Size on Fault Gouge Frictional Characteristics and Associated Acoustic Emission

Figure 8

Correlation between shear stress, AE energy, and displacement during slipping. Note: for Sample 1, the displacement value (unit: mm) is 6 times of its shear stress value. Similarly, the multiples of Samples 2–4 displacement are 5, 9, and 7, respectively. (a) Sample 1. (b) Sample 4. (c) Sample 2. (d) Sample 3.
