Abstract

The effects of dynamic predeformation on the dynamic behaviour of metallic glasses (MG) are investigated through split Hopkinson pressure bar (SHPB) tests. The results obtained on samples fractured in a single test are compared with those on samples fractured in two successive SHPB tests. They show a reduction in data scatter and an increase in maximum stress for predeformed samples.
