Abstract

Abstract

By means of Perzyna's brittle dynamic fracture constitutive model and Seaman's experimental results, a new model of brittle fracture is put forward. Numerical calculations of uranium spall processes during impact are carried with the new model. The computations are in fair agreement with the experimental results.
- brittle dynamic fracture,
- spallation,
- porosity
