Abstract
A relationship between the cumulative length of microcracks and the am plitude and duration of tensile impulse in spallation was established based on the application of statistical microdamage mechanics, which i ncluded a statistical formulation and dynamic laws of microdamage unde r loading. Since the degrees of spallation, called incipient, intermed iate and complete spallation, can be characterized by the cumulative l ength of microcracks, a physical interpretation of an empirical criter ion to spallation was presented.
