Simulation and experimental approach for shot velocity evaluation in ultrasonic shot peening [PDF]

Mécanique & Industries, 2011
The process of ultrasonic shot peening has been studied from two aspects: (a) a 3D numerical model of shot motion in the peening chamber based on the theory of granular gases, (b) an experimental setup developed for measuring shot velocity distribution in the chamber and impact locations on the peened surface.
