Basic Mechanisms of Spall from Near-Surface Explosions.

Abstract

The current state of the art on explosion-induced spall in geologic materials is examined, with emphasis on spall in soil due to near surface explosions. At present there is neither a generally accepted, precise, technical definition of, nor a generally accepted technique for predicting explosion-induced spall in soil. Several mechanisms can cause spall in soil, and the key to a better understanding of soil spall is a better understanding of soil tensile stress-strain behavior. (Author)
