Valid hardness measurements require actually causing plasticity. Thus, we must know the threshold and locus for the onset of plasticity. In this session, we use the Tresca criterion to understand the onset of plasticity for both Hertzian and conical indentation. These criteria guide our understanding of the minimum depth at which one can measure a meaningful hardness.
