Nanoindentation on Metals
The Stress-Strain Relationship: Theory & Experiments
Nanoindentation hardness and reduced modulus values provide vital information on the stress-strain relationship of materials and, by extension, their expected behavior during manufacturing and use.
This workshop focuses on discussing and demonstrating different theoretical and experimental approaches for deriving the stress-strain relationship in nanoscale indentation and compression experiments. The session recording includes a technical demonstration of the TI 980 TriboIndenter, which showcases
- Indentation and compression testing of metals;
- Analysis of stress-strain relationship of metals; and
- High load spherical indentation.
Quantifying Hardness and Elastic Deformation of Metals
The stress-strain relationship of materials provides vital information on their mechanical properties and enables a prediction of their behavior during manufacturing and use. It also characterizes deformation behavior during elastic loading, from yield at lower stress levels to work hardening and ultimate failure at higher levels. The relationship is typically determined in tensile tests on macroscopic samples.
Nanoindentation hardness and reduced modulus values are directly related to a material’s stress-strain relationship. However, in hardness tests, the deformation zone is non-uniform, unlike tensile tests that produce uniform stress and strain.
In this webinar, our invited speaker Dr. André Clausner, Fraunhofer Institute for Ceramic Technologies and Systems (IKTS), Germany, will provide an overview of theoretical approaches to this problem and discuss possibilities and pitfalls. We will demonstrate different experimental approaches for deriving the stress-strain relationship in nanoscale indentation and compression experiments on metals and metallic surfaces using the TI 980 TriboIndenter.
