Hi Sandeep, you can do this by Nanoindentation...this is available on all instruments. For literature, I would recommend you look at the section in chapter 3 of my book: 

Atomic Force Microscopy by Peter Eaton and Paul West, OUP (2010), ISBN:978-0-19-957045-4. There are also some examples of nanoindentation use to get elastic properties in chapter 7.

You can also find lots of other literature on this. If you have a modern bruker instrument, you could also look into QNM modes, which should be simpler and quicker to apply.

Pete.

Hi Sandeep,

Please check out the paper titled “The use of the PeakForce quantitative nanomechanical mapping AFM-based method for high-resolution Young’s modulus measurement of polymers,” published by a group of scientists mostly out of NPL in the UK. (NPL is the UK standards organization). Young et at, Meas. Sci Technol 22 (2011).
