Abstract
Vibration-triggered granular flow phenomena are widespread in nature. However, their influencing factors, triggering mechanisms, and flow characteristics remain incompletely elucidated. This study focuses on the triggering effect of near-static-threshold vibrations on shear instability in granular layers under different wettability conditions. The research reveals that under varying wetting conditions, vibrations with specific amplitudes and frequencies can induce system instability, leading to self-accelerating inertial flow or creep flow in the granular layer.
