Detection and Quantification of Damage in Metallic Structures by Laser-Generated Ultrasonics

According to the statistics on predecessors, the failures in metallic structures caused by fatigue cracks account for more than 90% [4]. According to the NNPE values calculated from each excitation point, the damage can be quantified successfully. [...]the changing of the laser beam spot caused by d...
