| Abstract: | A big electric-current apparatus which can output current of 0.15-0.25kA is discussed, a LY12 aluminium plate is heated by big electric-current, a heating, a heating rate from 27 to 7430℃/s can be obtained, the real-time recording technique of dynamic moire interferometry fringes under high heating rate by a high speed camera is studied, a recording frequency of 1000frame in a second is obtained. The temperature rising effect of structure irradiated by CW high power laser is simulated using both technology. It provides a new way to research some fundamental problems of structural mechanism of fracture. The experimental result indicates that it is possible for moire interferometry to measure dynamic deformation under high temperature condiation. |
