SPALL FRACTURE AND DYNAMIC RESPONSE OF MATERIALS

Abstract

The report describes the time-dependent fracture, or spalling, of materials as a result of dynamic response to shock-wave or impulse loading. From stress-wave and fracture-mechanics theory and assuming knowledge of the dynamic properties of the material, theories are developed to predict the stress at the spall plane. The cumulative, energy, stress-rate, and bond-breaking models for the prediction of spall fracture are described, along with the basic criteria of each model.
