Plane strain indentation of a Zr-based metallic glass: Experiments and numerical simulation

The response of a Zr-based metallic glass in instrumented plane strain indentation with a cylindrical indenter tip is studied experimentally. A recently developed constitutive model and simulation capability for metallic glasses is used to numerically calculate indentation load versus depth curves, and the evolution of corresponding shear-band patterns under the indenter. The numerical simulations are shown to compare very favorably with the corresponding experimental results.
