Plastic deformation and fracture of a bulk‐metallic glass rod with a concentric hollow in compression were investigated. The specimen exhibits a substantial plastic deformation before failure. A number of shear bands form at both outer and inner surfaces of the specimen. Fracture surface shows substantially ductile features. These results indicate that the bulk‐metallic glass has a high intrinsic ductility and the specimen's geometry can delay effectively premature fracture.
