Title: Shear strain in a shear band of a bulk-metallic glass in compression

Abstract

Using an infrared camera, the authors observe in situ the dynamic shear-banding operations in the geometrically constrained specimens of a bulk-metallic glass during compression at various strain rates. Based on the observed number of shear bands in a collection of simultaneous shear-banding operations that cause a serration, the authors calculate the shear strains in individual shear bands. The results demonstrate that the shear strain in a shear band is up to 10{sup 3}%-10{sup 4}% and dependent on strain rates. The higher the strain rates, the larger the strain in a shear band.
