| Abstract |
The laser peen forming (LPF) uses high-power pulsed laser beam replacing the tiny
medium balls to peen the surface of plate and generate compressive stress near the surface, the
metals respond to this residual stresses by elongating at the peened surface and effectively bend the
overall shape. In this paper, the deforming process of metal plate induced by repetitive pulsed laser
was discussed from theory firstly, and the bending mechanism of LPF was investigated. Then a
mathematical model of bending curvature concerning the depth of residual stress was presented, the
influence of residual stresses on the deformation of plate was analyzed. Lastly, the
line-track-peening experiment for SUS 304 plate was carried out to evaluate the reasonability of the
theoretical analysis model. |
