Indentation University Session 3: Basic Instrumented Indentation

In Session 3 of the KLA Instruments Indentation University, we walk you through the theory of basic instrumented indentation (nanoindentation), with special attention paid to the Oliver-Pharr technique.

About this webinar

Session 3 provides a theoretical approach to nanoindentation testing, including hardness testing, Young’s modulus (elastic modulus) testing, and determining the yield stress of a material. Different material properties, including grain structure, have an impact on nanomechanical properties. The discussion includes how instrumented indenters work, including definition and formulas for various nanoindentation parameters, and how hardness testing is typically conducted. A case study involving polycarbonate, Pyrex, fused silica, <111> silicon, and nanocrystalline nickel is reviewed.

Note: for Session 3, it is recommended to view the following Indentation University webinar as background for the discussion:
