摘 要：A new parameter, i.e., tearing toughness, was employed to characterize the mechanical properties of some ductile metals（Cu, Cu–2 wt% Be, Cu–Al alloys, and some steels） by using three-leg trousers tearing tests. The experimental results demonstrate that their tearing toughness is not a physical constant and shows a close relationship with the materials’ types and microstructures. It can be inferred that the tearing toughness of different ductile metals has their respective variation range, expectantly, and may be represented by the comprehensive mechanical properties of strength and ductility for various ductile materials.
