Abstract
Results are presented from an experimental study of the spallation strength of lead (S1) and a metal-ceramic (Al + 20% SiC) as representatives of mate rials that are more ductile and brittle than those studied before. The dime nsions of the samples changed by factors of 4-5. It was found that during f racture of these materials under high velocity one-dimensional deformation, significant scaling effects are observed which originate in the energy cha racteristics.
