In order to study the dynamic strain on 2024 aluminum alloy surface induced by a pulsed laser shock wave, the pulsed laser is used to impact on a 2024 aluminum alloy sample, and the dynamic strain on the 2024 aluminum alloy surface which is under the effect of the pulsed laser shock is measured by a polyoing lidene fluoride (PVDF) piezoelectric sensor. A dynamic strain model of 2024 aluminum alloy surface loaded by the pulsed laser shock wave is established and verified by experimental data. The results show that the laser shock wave and surface wave can′t couple by adjusting the parameters of laser pulse. The relationship curve of the dynamic stress-strain of 2024 aluminum alloy under high strain rate of pulsed laser shock wave is similar to the static stress-strain relationship curve of 2024 aluminum alloy under static tensile condition. The experimental results are consistent with the dynamic strain model of 2024 aluminum alloy surface loaded by the pulsed laser shock wave.
