【 摘 要 】

Slip avalanches occur in both crystalline and amorphous solids. Slip avalanches and avalanches in other systems are thought to be critical phenomena linked to a nonequilibrium phase transition. In this thesis we explore some temporal properties of experimental slip avalanche dynamics. These properties include aftershocks and foreshocks of slip avalanches in a bulk metallic glass, oscillations in the experimental setup affecting the ongoing avalanche dynamics, and temporal clustering of avalanches in systems with dynamic weakening.
