A finite element model for simulation of shot-peening

摘要

Shot-peening is an industrial surface treatment widely used in the aerospace industry, but still not considered during the dimensioning phase of mechanical parts. Benefits are used to increase safety margins only; today there is an industrial need for dimensioning part optimization. This work is the first part of an industrial project which aims at using numerical simulation to develop a complete model including the the simulation of the process and then the cyclic loading of a complex geometric part made of INCONEL 718 (IN718) nickel-based alloy.
