CRATERING AND PENETRATION

Abstract

Theoretical and experimental work on cratering and penetration is reported. Work is reported in six areas as follows. 1. Energy Partitioning in Impact. Techniques and results are summarized for measurements of target heating, target mass loss, spray energy, and recrystallization and strain energy. 2. Material Properties. The formulation of a general equation describing the relation between pressure, specific volume, and internal energy of a material is reported and the comparison with existing data for gases, for static compression of liquids and metals, and for shock compression of metals is reviewed. 3. Wave Motion in Impact. Theoretical and experimental studies of wave motion in idealized systems which can be described by one space variable are summarized. 4. Transient Measurements in Impact. Work on the measurement of subsurface pressure waves using buried barium-titanate pressuretransducers is summarized. 5. Spray-Particle Generation. Work on the role of spray particles in impact flash is summarized. A preliminary report is given on the generation of spray particles and material flow in the penetration of thin targets.
