Abstract

The influence of temperature and strain rate on a spall strength in a single crystal and polycrystal of aluminum is studied by means of molecular dynamics. The different behavior of the dynamic spall strength of the single and polycrystal was observed in shock-wave experiments at a temperature near the melting temperature. The spall strength of polycrystal tends to be zero at the melting temperature, while for single crystal temperature influences on the spall strength sufficiently less and considerable overheating takes place. This work is devoted to explain such effect.
