The surface roughness of the laser shock peened medium has effect on the high frequency of laser-generated surface acoustic waves. As the impact times of the laser shock peening increase, the surface roughness has little effect on the dispersion of laser-generated surface acoustic waves. From the theoretical curve and experiment curve, it can ...
