Abstract
A dynamic punch test technique using a compression split Hopkinson bar is presented. Thin Ti-6Al-4V disks are loaded with three punches with different nose radii both statically and dynamically. The fixtures are designed with viewports to accommodate optical displacement and strain measurement on the back surface of the specimen using three dimensional digital image correlation (3D DIC). The fixtures are designed to match the impedance of the Hopkinson bars used for dynamic tests. Displacements measured using image correlation are compared to those calculated from split Hopkinson bar wave data. Full-field strain data from these tests are used in the construction of a fracture locus for Ti-6Al-4V. Results from these tests also can be used to evaluate constitutive and failure models for Ti-6Al-4V.
