Abstract
The indentation response of a mica‐containing glass‐ceramic is studied. In this type of material, Hertzian cone cracks, which normally occur in brittle materials that have been loaded with a hard spherical indenter, are suppressed in favor of distributed subsurface damage, which is indicative of yield. Theoretical analysis, finite‐element modeling, and experimental results are used to establish a connection between the macroscopic behavior of the material and events that occur on a microstructural scale. This association is achieved by first determining the macroscopic material properties, such as the yield stress and the strain‐hardening index, in terms of the microstructure. Then, these properties are used to predict the macroscopic indentation response of the material. Thus, the problem is partitioned into microstructural and macroscopic domains. This work is particularly relevant to the design of structural ceramics in machining, wear, and bearings applications.
