Abstract
Shot Peening is used as one of the most common surface treatment processes for mechanical and structural elements. In Shot Peening Process, the effect of surface treatments can roughly be divided into three factors, projection, particles, and specimens. These factors have complex effects on each other, so it is difficult to understand the specific factor to control the process. In this study, we carried out the numerical simulation of Shot Peening processes. Especially, we focused on the relation between moving shots and surface modification. The results show that the locations of particle collision on the specimen distributed broadly. This is due to the collision between shot particles flying from nozzle to specimen.
