摘要	In this work, the compressive global plasticity depending on different settings of notch cluster was investigated on Zr-based metallic glass by experiment and finite element simulation. In experiment, it was found that a large plasticity could be generated by changing the distance of notch pairs which could make the shear bands (SBs) interact with each other and block the rapid shear banding. By introducing the Mohr-Coulomb yielding criterion and the associated flow rule, an elastic-plastic model was built up to describe deformation process for all specimens by means of finite element method (FEM). Combined with the experimental results, it demonstrated that the large plasticity was attributed to the intersection of multiple SBs which was caused by V-shaped plastic strain regions according to FEM results. Finally, conclusive parameters were tentatively proposed to work as the direct and fundamental basis for fabrication of new metallic glass based porous materials or composites. (C) 2015 Elsevier B.V.
