Numerical Simulation of the Depth-Sensing Indentation Test with Knoop Indenter [PDF]
Metals, 2018 Depth-sensing indentation (DSI) technique allows easy and reliable determination of two mechanical properties of materials: hardness and Young’s modulus. Most of the studies are focusing on the Vickers, Berkovich, and conical indenter geometries. In case of Knoop indenter, the existing experimental and numerical studies are scarce.
