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. (c) 2005 Acta Materialia Tnc. Published by Elsevier Ltd. All rights reserved.
