Effect of shot peening on <i>J</i>-integral and crack propagation rate of semi-elliptic surface crack on Ti6Al4V

Effect of shot peening on <i>J</i>-integral and crack propagation rate of semi-elliptic surface crack on Ti6Al4V

Considering the residual stress, residual strain and residual strain energy, the influence of shot peening on the <i>J</i>-integral parameters of semi-elliptic surface crack front was quantitatively calculated and analyzed. The shot peening process was simulated, the fatigue crack was ge...
