Notes:
In this paper, the deformation fields of LY12 crack samples loaded by an SHTB arereal-time investigated with the time interval of 10 µs by an optical system, which consists of ahigh-speed camera, a flash light, a frame grabber and a synchronization device with the delay-timeless than microsecond. The cracks are preset by using the three-points bending method in a MTSfatigue machine. The crack is 2mm long with a flare angle of 60 degree. During the experiments,the dynamic deformation images are captured by the high speed camera and analyzed by newlydeveloped software based on Digital Correlation theory. And the displacements fields nearcrack-tips according to the changes of the flare angle and radius during the impact process areobtained. Experimental results acquired in this paper are proofed, by compared with the theoreticalcalculations
