✦ Synopsis

Consideration is given to non-stationary shock wave on spallation. Spall strength can be written as (i) pressure * particle velocity diagram in a one-dimensional case, and (ii) pressure * angle of turn #ow diagram in a two-dimensional case. Experimental procedure involves (i) loading of the explosive by sliding detonation and (ii) orthogonal #ash X-raying. In this way, some metals in particular low-melting ones and plastics as well as liquids have been studied based on the present results and those of other researchers. The dependences of spall strength * deformation rate have been obtained for substances studied in the form of power or linear functions. Some aspects of spallation and of accompanying e!ects on the base relations obtained are discussed.
