Cyclic Indentation Behavior of Layered Nanocomposites: Viscoplastic Numerical Study

Abstract

The indentation behavior of layered metal/ceramic nanocomposites was studied. The primary objective was to examine the evolving plastic deformation in the ductile metal constrained by the hard ceramic layers, during indentation cycling with respect to fixed maximum and minimum indentation loads. The model consists of alternating aluminum and silicon carbide thin films on a silicon substrate, with the
