Abstract Aiming at the elongation problem of the integral panel of large aircraft based on shot peen forming, this
article from the factors influencing the integral panel elongation deformation in shot peen forming, through the comparison
of theoretical calculation of wingspan shot peen forming strain and experimental data of elongation deformation, elongation
law of integral panel in shot peen forming is concluded.
