Finite Element Simulation of Surface Roughness of an Al-5052 Plate Processed by Shot Peening

The evolution of surface roughness of Al-5052 plate subjected to shot peening was simulated by means of LS-DYNA, and the influences of variation of parameters, such as the size of shot, the velocity of shot, the density of shot, strength coefficient, strain hardening exponent, friction coefficient and incident angle, were investigated. Moreover, the effect of space ratio of two shots was also studied. The simulated results, analytical results and experimental results were compared, and the results showed that the simulated results were agreement with experimental results and analytical results, that the important roles played by the shot size and shot velocity, but to a much lesser extent by the other parameters.
