【 摘 要 】

The plastic deformation of shot peened pure titanium and deformed texture along the depth were simulated by finite element method(FEM) and visco-plasticity self-consistent(VPSC) method respectively. The results show that the stress state is compressive stress in three principle directions from subsurface to the depth at 600μm. The strain state is a complicated strain state and exhibits strain gradient along the depth. Strain gradient results in texture gradient in shot peened pure titanium. The texture in pure titanium with initial typical recrystallized texture is strengthened after shot peening, with strongest texture at the depth where the maximum absolute values of strain components exist.
