SUMMARY
The measurement of Young's modulus for powders, particularly those with a particle size D50 around 50 microns, requires specialized techniques due to the limitations of quasi-static methods like compression and tensile testing. Atomic force microscopy (AFM) is a recommended approach, utilizing a microfabricated tip to elastically indent the sample to depths of less than 1 micron. Additionally, dynamic mechanical analysis (DMA) within a material pocket offers another viable method for assessing the mechanical properties of powdered materials.
