Abstract

The objective of this paper is to study the effect of shot peening on components made of Aluminum (Al2024) material. Shot peening is one of the process to optimize fatigue life of component. The FEA model was developed for assessing the effect of shot size, velocity, angle and distance on compressive stresses induced in the component. The compressive stress induced inside the component increase the fatigue life of material. The model was validated using physical experimentation. The residual stresses were measured using hole-drilling strain gauge method and fatigue life was estimated using 3-point bending test.
