Knoop Hardness-Apparent Yield Stress Relationship in Ceramics
In Tabor's classical studies of the deformation of metals, the yield stress (Y) and hardness (H) were shown to be related according to H/Y ≈ 3 for complete or fully plastic deformation. Since then it has been anecdotally shown for ceramics that this ratio is
