PULSED HOLOGRAPHIC AND SPECKLE INTERFEROMETRY TO INVESTIGATE THE DEFORMATION ON PLATES

The major objective of this study is to investigate the dynamic experimental technique about the deformation, of the finite-circular metal plates after normal impact. Holographic interferometry and defoeus speckle photography are utilized to record "he transient response of plates. Synchronization of the event with the pulses from the new type DJ-1 ruby laser is accomplished with the electronical equipment designed by the authors. Hot.kmson type instrumented bar loading apparatus is used to determine the lo...
