Examining the Effect of Pileup on the Accuracy of Sharp Indentation Testing

Figure 2

Displacement fields at indentation depth of 3 μm for conical indenter (a), Vickers indenter (b), and Berkovich indenter (c). Only half of each model is shown. Note that the negative values of displacement (U3) indicate pileup of the material.
