Abstract:

The report summarizes the results of the measurement of high strain rate plastic flow properties and ductility in a uniaxial, homogeneous stress system and of a study of deformation mechanics in high energy rate forming operations. Presented for the first time are the results of a study made on the energy transfer process at a liquid-metal interface. It was found that separation of the liquid and the metal occurs only after a number of wave reflections have taken place. Finally, the report concludes with a discussion of some of the major problems associated with high energy forming processes which remain to be investigated before these processes can be adequately understood.
