N2 - In the present contribution intrinsic and extrinsic size effects on the shear band propagation behavior in metallic glasses arestudied. To this end, a thermodynamically consistent finite strain viscoplasticity model is formulated. The strongly coupled and highly nonlinearsystem of field equations consisting of deformation, free volume and plastic strain field, is implemented into the finite element method,resulting in a non-local model formulation. The results show that the proposed continuum plasticity model is well suited to predict stable ordelayed shear localization process with decreasing sample size. With an underlying microstructure, the material behavior in metallic glassescan be significantly influenced, as demonstrated numerically in this contribution on the basis of porous structures.
