Inspired by adhesive-stacking technology, a parallel epoxy-amorphous foil laminate was proposed to extract the shear flow curves of the amorphous foil. Based on the equal strain assumption of the composite parallel model, the relationship between the single-layer material and the laminate was mapped. Then the pure shear flow curve of the laminate was mapped to the single-layer sheet to solve for its pure shear flow curve. The accuracy of the pure shear flow curve of the amorphous alloy was verified by comparing the finite element simulated results with the experiment results. The approach offers a practical route for solving the pure shear flow curves of single-layer amorphous foils. Furthermore, the threshold in the maximum shear stress ductile fracture criterion was determined by finite element simulation of pure shear fracture curves of the laminates, and blanking fracture in Fe-based amorphous alloy laminates was successfully predicted.
