Mechanism and Influencing Factors of Frictional Energy Dissipation in Multilayer Ultrasonic Welding

Shanghai Jiaotong Daxue xuebao, 2022
In multilayer ultrasonic welding, the sonotrode presses on metal sheets and drives the sheets to produce ultrasonic vibration. Then, each contact interface generates heat, produces plastic deformation, and forms solid-state bonding.

Frictional Weakening of Vibrated Granular Flows

Physical Review Letters, 2023
We computationally study the frictional properties of sheared granular media subjected to harmonic vibration applied at the boundary. Such vibrations are thought to play an important role in weakening flows, yet the independent effects of amplitude, frequency, and pressure on the process have remained unclear.
