Measurement method verification of the Al7075 samples, when the shot type is S230 and the moving speed of the nozzle is 800 mm/min. (a) Deformation of the Al7075 strip after shot peening. (a) The robust method was verified by the residual stress; Vis equal to 38 m/s, corresponding to P being equal to 2.5 bar. (b) The microstructures at the surface and the robust method were verified by the surface roughness with different shot velocities (corresponding to air pressure).
