| Abstract: | The moire inferometry method is used to measure the displacement field near the tip of crack in the interface of himaterial welding specimen(copper and steel) under three point beending olad, based on the hologram grating (f= 1200 L/mm). It is showed that the distribution of displacement is complicated and not symmetric in the tip of crack. The moire interferometry method is complicated and not symmetric in the tip of crack. The moire interferometry method is proved that it's suitable to measure the inplane displacement o?crack tip. |
