000015370 520__ $$2eng$$aIn the present contribution intrinsic and extrinsic size effects on the shear band propagation behavior in metallic glasses are studied. To this end, a thermodynamically consistent finite strain viscoplasticity model is formulated. The strongly coupled and highly nonlinear system 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 or delayed shear localization process with decreasing sample size. With an underlying microstructure, the material behavior in metallic glasses can be significantly influenced, as demonstrated numerically in this contribution on the basis of porous structures.
