Abstract : Work is reported in the following areas: (1) Wave propagation in non-linear materials: A previously reported study of wave motion in a bar is summarized and an outline of the extension of the work to more complicated systems is given. (2) Energy distribution in cratering:A summary of measurements of energy partitioning inin the impact of steel into lead is given. (3) Transient measurements in hypervelocity impact: Two complete reports on projects for the measurement of subsurface pressure and density and subsurface wave propagation are given. (4) Spray particle measurements: A summary of efforts to utilize spray particles for impact studies is given. It is concluded that it is impractical to use spray particles for impact studies if trajectory studies must be used to measure particle properties. Research on the use of spray articles to investigate meteror physics is summarized. (Author)
