Indentation University Session 22: Theory of Measuring Stress-Strain Curves by Nanoindentation

In Session 22 of the KLA Instruments Indentation University series, recent advances in nanoindentation techniques can be used to measure the entire stress-strain curve, even within a single metal grain.  

About This Webinar

Session 22 covers the motivation for and the theory behind measurements of stress-strain using nanoindentation, and how measurements of force, displacement, and stiffness can be interpreted to arrive at the stress-strain curve. This patented method was developed by KLA Instruments Senior Application Scientist Jennifer Hay, who leads the discussion of this important technique.

Note: for Session 22, it is recommended to view the following Indentation University webinars as background for the discussion:

Attend This Indentation University Webinar and You Will:

  • Understand the motivation behind this technique
  • Understand why the flat punch tip is critical for this measurement
  • Understand the use of elastic contact theory in defining stress and strain, and how to quantify the degree of plasticity
  • Learn how finite element analysis can be used to simulate the effect of elastic-to-plastic contact
  • Learn guidelines for setting up your stress-strain experiments

About the Speaker

Jennifer Hay is a Senior Applications Scientist for KLA Instruments, specializing in nanoindentation. Prior to joining KLA, she held similar positions at Nanomechanics, Keysight, Agilent, and MTS Systems Corporation. Jennifer has worked in the field of nanoindentation since 1996, advancing standardization while also developing methodology for new applications including thin films, polymers, gels, and biomaterials. Mrs. Hay served as the chair for the MEMS/Nanomechanics technical division of the Society of Experimental Mechanics (SEM), and she has authored many journal articles on nanoindentation, including an invited feature series in the SEM journal Experimental Techniques.
