摘要

Zr41.2Ti13.8Cu12.5Ni10Be22.5 bulk metallic glass (BMG) alloy obeys different yield criterions under different stress states. In order to accurately describe yield behavior of BMG alloy and clarify the effect of middle principal stress on material yield and fracture, Unified Strength Theory is introduced to study plastic yield behavior of BMG alloy. The unified expression of yield function and its corresponding yield locus on π plane of Zr41.2Ti13.8Cu12.5Ni10Be22.5 BMG alloy are obtained.
