Abstract:

The principal goal of this research is to experimentally measure the three-dimensional transient deformation processes that occur in armor systems undergoing a range of dynamic loading conditions. The development of a 3-D image correlation system using digital cameras capable of acquiring images every 5 nano-seconds were used. Due to the nature of the cameras. extensive algorithms for the removable of image distortions were required. The image correlation technology was transferred to army personal through a one year sabbatical at ARLs Aberdeen research facility by the principal investigator.
