Abstract
The characterization of the inelastic response of materials to high rates of loading is a challenging engineering problem. As the load rate increases, the interpretation of the data recovered from the experiment become more difficult. At very high rates of loading, even the inertia of the test specimen must be accounted for in the interpretation of the data. The Taylor impact experiment is specifically designed to exploit the inertia of the specimen to produce very high loading rates and has been used to study the high strain (50%), high strain rate (103-4) behavior of materials for many years. Many high-rate loading problems produce failure in the material. Continuum codes have been used to design sleeved impact specimens to study the failure of materials under high rates of loading. Ductile core materials are used as drivers to control rupture of more brittle sleeves of the material of interest. Annealed copper cores are used to drive dynamic failure in AF1410 steel. High rate plastic deformation data are presented for the driver and the sleeve together with the fracture data.
