Computer Vision Quantification of Complex Fracture

Abstract

Ballistic impact and other Army-relevant impact conditions result in complex multicrack fractures. These fractures are typically analyzed via qualitative analysis of postmortem and high-speed in-situ photography. Computer vision techniques to extract and digitize cracks are demonstrated, and the resulting features are analyzed statistically to both extract underlying physics and allow quantitative comparison between experiments and simulations. Two case studies applying the technique are presented: in-situ X-ray imagery of boron carbide ceramic under ballistic impact and simulations modeling fracture in skullcap.
