Measurement of Youngs Modulus of Powders

How do we measure the young's modulus of powders (particle size D50 is around 50 microns)?

Quasi static methods like compression , tensile etc are not recommended for powders like materials. WHat modifications do we need if one wants to use compression method ?

Hi aruneshk, welcome to PF. One possible approach is atomic force microscopy, in which one elastically indents the sample to a depth of <<1 micron by using a microfabricated tip.

Another method that springs to mind is the use of dynamic mechanical analysis within a material pocket.
