In this study, punch test is employed to study the deformation and fracture mechanism of materials, taking metallic glasses as an example, under the multiaxial loading. On one hand, shear bands, as the type of deformation behaviors, are observed to initiate and propagate along two directions to form the grid pattern in the three-dimensional space. On the other hand, the further understanding focuses on the deformation and fracture mechanism of materials under punch loading. Finally, the intrinsic origin is explored in the physical interest.
► Deformation and fracture of amorphous material is characterized under the multiaxial stress. ► Shear bands are observed in the three-dimensional space. ► Competitive process between tensile normal stress and shear stress is convinced. ► Inherent mechanism is exploited to clarify the intrinsic physical interest.
