A bifurcation analysis is used to understand the damage realized in flatplate gas-gun specimens that were machined from a highly-textured plate stock of Zr. These low-symmetry material specimens were tested to insipient failure and subsequently soft-recovered. Post-mortem data sets consisting of EBSD imaging of metallographic samples cut from the recovered targets show very different texture-dependent damage morphologies depending on the initial texturekarget orientation at impact.
