Zr- based metallic glass exhibiting room temperature tensile plasticity is studied for mode I and mode II type fracture. Scanning electron micrographs of the fracture surfaces are examined to reveal the operative fracture mechanism and the relevant process zone size. We develop a finite element model which predicts the Shear band/crack trajectories in mixed mode failure. Specific material parameters in a simulation may be used to correctly predict the crack path and stress distributions ahead of the crack tip. This predictive model can be used to understand the mixed mode fracture response.
