Abstract
Abstract : X-ray computed tomography (XCT) has been shown to be an important non-destructive evaluation (NDE) technique for revealing the spatial distribution of ballistically-induced damage in metals, ceramics, and encapsulated ceramic structures. Previous and ongoing work in this area includes assessment of ballistically induced damage in relatively lightweight individual ceramic targets and ceramic armor panels. In this report, the ballistic damage in a novel Mg alloy sample was completely scanned and extensively evaluated using XCT two-dimensional and three-dimensional (3-D) analysis. Features of the damage were correlated with physical processes of damage initiation and growth. The study of this sample is the first known NDE of ballistic damage in this type of lightweight Mg alloy material by XCT or any other NDE method. XCT scans and analyses of damage in the sample will be shown and discussed. This will include virtual 3-D solid visualizations and some quantitative analysis of damage features.
