註釋Parameters governing the failure of thin metal plates under the impact of highspeed fragments are studied; special emphasis is placed on the lightweight structural alloys. The geometrical features of the perforations, together with the spatial, mass, and velocity distributions of the ejecta produced in the perforation process, are of immediate interest. Since these variables are strongly dependent on the characteristics of the impacting projectile as well as the physical properties of the target material, a variety of experimental approaches to the problem are clearly evident. In an effort to systematize the approach and at the same time gain information that will be of immediate practical value, a few select target materials are currently being investigated under impact conditions that involve the same projectile geometry but different impact velocities.
