OPTIMIZATION OF FATIGUE LIFE OF PISTON THROUGH SHOT PEENING: PREDICTION & ANALYSIS

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 assessin g the effect of shot size,velocity,angle and distance on compressive stresses induced in the com ponent. The compressive stress induced inside the component increase the fatigue life of material . The model was validated using physical experimentation. The residual stresses were measure d using hole-drilling strain gauge method and fatigue life was estimated using 3-point bending te st. https://www.ijiert.org/paper-details?paper_id=14050
