Indentation University Session 5: Elastic Contact Mechanics

In Session 5 of the KLA Instruments Indentation University, we cover the theoretical and historical background of elastic contact mechanics as it pertains to nanoindentation testing. Special solutions of Sneddon’s analysis are defined and discussed.

About this webinar

Session 5 starts with the much-cited publication by Dr. Ian Sneddon, “The Relation between Load and Penetration in the Axisymmetric Boussinesq Problem for a Punch of Arbitrary Profile”, one of the most-cited articles in the field of indentation testing. Sneddon’s solution is then applied to nanoindentation testing, focusing on relevant geometry examples. Note that this webinar is heavy on theory and equations.

Note: for Session 5, it is recommended to view the following Indentation University webinar as background for the discussion:

Attend this Indentation University webinar and you will:

  • Understand the relationship between load, contact geometry, and the elastic properties of the contacting material
  • Learn how elastic contact theory is applied to derive nanoindentation testing results
  • Understand how elastic contact theory is applicable even in cases of plastic deformation
  • Learn about the three solutions of Sneddon’s analysis that pertain to nanoindentation

About the speaker

Jennifer Hay — Senior Application Scientist

Jennifer Hay is a Senior Applications Scientist for KLA Instruments, specializing in nano-indentation. Prior to joining KLA, she held similar positions at Nanomechanics, Keysight, Agilent, and MTS Systems Corporation.  Jennifer has worked in the field of nano-indentation 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 nano-indentation, including an invited feature series in the SEM journal Experimental Techniques.
