Abstract

A method for executing water jet peening for giving an impact force to a surface of a structure member by a crushing pressure of a water jet and cavitation and improving residual stress, or washing, or reforming said surface,wherein said water jet peening is executed so as to make a natural frequency of oscillation of said structure member and a excitation frequency of oscillation of water jet peening different from each other.
