Summary

The main objective of this paper is to provide an updated overview of the recent and more interesting damage characterization results revealed from a continuing non-destructive examination of encapsulated TiB2 ceramic targets impacted with 32gm high velocity projectiles with an L/D ratio of 20. X-ray computed tomography, XCT, and advanced voxel analysis and visualization software (Volume Graphics StudioMax vl.2.1) techniques are utilized to provide unprecedented diagnostic flexibility into the volumetric characterization and analysis of complex in situ ballistic impact damage. These techniques facilitate the creation of digitally rendered 3D solid object reconstructions, arbitrary virtual planar sectioning, variable transparency and segmentation of both projectile fragment and cracking damage morphology and distribution, virtual metrology and 3D visualization of damage features of interest, and impact induced porosity analysis. Examples of several of these unique NDE damage observations are provided and discussed for improved appreciation, understanding, and cognitive visualization of the complex ballistic impact damage occurring in impacted TiB2 armor ceramic targets.
