Improving mechanical characteristics of a Zr based metallic glass under dynamic conditions by dynamic predeformation

摘要

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.
