    Abstract

    The investigation of the dynamic tensile or spallation response of materials is generally characterized by the measurement of reload signals during rear surface velocity experiments, or postmortem by metallography of sectioned target assemblies. The latter can only reveal features in twodimensions, although serial sectioning can generate a three-dimensional representation of the spalled region. By contrast, X-ray tomography can generate three-dimensional images without the need for sectioning. In this investigation, we combine rear surface heterodyne velocimetry measurements with X-ray tomography of recovered Ti-6Al-4V targets to identify tensile failure mechanisms during dynamic loading. © 2012 American Institute of Physics.
