Past materials research efforts have focused on developing constitutive laws and numerical solvers for representing material behavior, but less attention has been paid to the representation of material microstructure. The mechanisms of deformation and damage are strongly dependent on material microstructure. We investigate the plastic behavior and texture anisotropy in tin under dynamic loading over a range of strains. A set of tin Taylor cylinders tested to different strains is studied. The microstructural changes along the Taylor cylinders depend on the strain imposed. Detailed Electron Backscatter Diffraction analysis allow us to understand better the texture evolution with dynamic strain in tin and helps improve models that capture the physics of high-rate material response during highly dynamic events. Statistical distributions of microstructurally relevant features in tin will be discussed in relation to the localization of plastic deformation and damage nucleation and evolution, with focus on grain boundaries and crystallographic orientations.
