Abstract:  
ABSTRACT: A model of shot peening on particle reinforced TiB2/Al composite material was built with ANSYS/LS-DYNA software. The simulated residual stress matched quit well with experiment data. Typical residual stress field which was caused by shot peening had been observed in the plastic deformation zone. Analysis showed that tensile stresses generated inside some reinforced particulates of the surface layer. Besides, in the plastic deformation zone, residual stresses in TiB2 particles were generally greater than that in Al matrix. The reason could be ascribed to the difference of mechanical properties of these two materials. Keywords: TiB2/Al composite, shot peening simulation
