| Abstract: | The dynamic digital speckle pattern interferometry(DSPI) has been achieved by using the instantaneous image capturing technique. The measurement of out of plane displacement field of circular restrained plate with a cross point impact loading is completed. The results of dynamic finite element method show good agreement with those of experiments. |
