Abstract : Progress in the development of new approaches to the analysis and experimental studies of the deformation, failure, and processing of structural materials under high loading rates has been reviewed. Advances in elucidation of the response of materials to high loading rates, with a focus on ceramics, are included. The field of shock synthesis and processing, and directions of future work, have been considered. Special emphasis has been given to materials deformation modes, other prefailure modes, and fracture mechanisms, since these are the concepts that are key to hydrocode development and accurate modeling of real material behavior under high loading-rate conditions.
