Deformation and fracture behaviors of Zr-based metallic glasses under different constraint shear angles

•The applied constraint shear tests were performed to investigate the deformation and fracture behaviors of Zr35Ti30Be27.5Cu7.5 MGs under different ratio of the shear stress to normal stress.•The Mohr-Coulomb criterion successfully described the positive relationship between the fracture strength and the applied shear angles, which is consistent with experimental results.•The large shear stress in dynamic stress equilibrium system can facilitate the amount of more free volume generation in MGs, manifesting as a large number of serration events.
