Nanoindentation is a common technique for measuring the Young’s modulus and hardness of metals. With recent advancements, nanoindentation can now be used to measure the entire stress-strain curve, even within a single metal grain. Join Sr. Application Scientist Jennifer Hay for a discussion of the theory behind this new measurement, and how nanoindentation measurements of force, displacement, and stiffness can be interpreted to arrive at the stress-strain curve.
