Abstract

In our presentation we will concentrate on the dynamical experi mental techniques about the deformation of the finite-circular metal plates after normal impact . Holographic interferometry and defocused speckle photography are applied to get the full field response. Synchronization is accomplished with the electronical equipment specially designed by author. A new loading apparatus is developed to determine the transverse impact waveforms.
