Abstract:  
Three-dimensional model of single and multiple shot is developed for shot peening. Shot peening is analyzed with steel shot for three different materials, Steel, Al-7075 and Ti-6Al-4V. The diameter and velocity of shot were varied to evaluate the shot peening behavior. LS Dyna was employed to carry out the numerical simulation of shot peening process. The study examined the induced residual stresses and plastic strains produced during shot peening. The numerical results showed reasonable agreement with the existing theoretical model of shot peening. The investigation showed that velocity of shot dominates the diameter of shot.
