Creep, Elastic Modulus & Stiffness
Instrumented indentation allows to study the creep behavior of material. When the maximum load is kept constant for a given time prior to unloading, a "creeping" material will show a plateau.
The displacement that occurs during that given time can precisely be measured and the creep computed.
The elastic modulus and the stiffness can also be extracted from the data curve given that the Poisson coefficient is known.
