Instrumented indentation (nanoindentation):

          Elastic modulus & stiffness
          Creep

Tensile testing:

          Elastic modulus
          Creep & elongation

When a sample cannot be tested using conventional tensile testing method, nanoindentation can be used to measure the creep and the elastic modulus.  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's ratio is known.
