Abstract:

An experimental investigation was conducted of crater growth and ejecta cloud formation from the impact of 3.2 mm aluminum spheres on thick aluminum targets at 7 kmsec. Crater growth and transient shape were determined through sequential flash x-rays. Growth followed a decaying exponential pattern, and the tangent angle to the crater wall at the target surface remained virtually constant. Relationships between ejecta-cloud parameters and crater diameters were investigated. Cloud-edge motion was determined and an effort made to determine particle origin. Velocities of discrete particles in the cloud were determined.
