摘要
A method of evaluating impact force input to a workpiece member with a laser irradiated in laser peening processing is provided. This evaluation method includes a signal acquiring step, an input function calculating step, and an evaluating step. In the signal acquiring step, a detected waveform is acquired. The detected waveform is output during the laser peening processing by an AE sensor that detects an elastic wave generated in the workpiece member. In the input function calculating step, an input function I(t) by laser irradiation is calculated. In the evaluating step, impact force is evaluated using the input function I(t) by the laser irradiation.
