Finite element simulation of peen forming process for the saddle shape

Shot peen forming is a viable method to form the complex wing skin panels of modern aircrafts. In this paper, an equivalent thermal loading method has been used to simulate the peen forming process for the saddle shape. The effects of peening bands on the spanwise curvature and chordwise curvature have been qualitatively analyzed. Result show that the thermal loading model can be used to simulate the deformation tendency of the peen forming and predict the elongation at the peening band.
