摘要：

The large area delaminated (two layers) and non-delaminated samples of 1 mm-thick aluminium alloy 2024 were shocked by pulse laser, the restricted layer and the absorbing layer were coated on the surface of the samples, and the PVDF sensors were set on the facing of a quilt of the samples. The signs of laser shock waves were transmitted to the computer by the oscillograph. The results indicated that can be effective detected by laser shock waves, and the math model of hierarchical sheet-metal by laser shock wave was fundamentally developed. A new method to detect the large area delaminated samples was provided, which has the definite engineering importance.
