Brinell testing
Process Testing method for materials in which a carbide ball is pressed down against the surface and creates an indentation which is measured to estimate the material’s Brinell hardness.

Surface-destructive testing
Knoop testing
Process Testing method for materials in which an indenter whose tip is shaped like an equilateral pyramid creates a depression whose diagonal is translated to Knoop hardness.
Rockwell Testing
Process Testing method for materials where an indenter is pressed against the material in two rounds and the difference in depth is measured and compared to estimate the material’s Rockwell Hardness.
Vickers testing
Process Testing method for materials in which an indenter whose tip is shaped like a pyramid creates a depression whose area is translated into Vickers hardness.
