STUDIES OF THE THEORY OF SPALLATION.
Abstract
This is the final report on the studies of the theory of spallation which have been performed by the Missile Systems Division of Republic Aviation Corporation. A literature survey on spallation has also been prepared as part of this contract and has already been submitted to AFSWC. The process of spallation and its separation into the two phenomena of stresswave propagation in solid materials and fracture under dynamic loading are described in Section II. A brief account of the present state of knowledge concerning fracture, as well as the experimental data that form the basis of the theoretical development given in Section III and the fracture criterion that is to be used, is also given in Section II. A comprehensive theoretical derivation of Zhurkov's law of timedependent fracture is presented in Section III. In Sections IV and V, the results of this analysis and other factors entering into fracture processes are discussed. A brief account of some experimental methods that could be used to study spallation is given in Section VI. (Author)
