hardness vs compound vs Elastic modulus
hardness vs compound vs Elastic modulus
(OP)
Hi,I have a question on the relation of hardness and elastic modulus,I had ever got the idea from somewhere that the mechnical property of rubber is determined by the hardness,and now I am doubt about it.Do you agree the idea that same hardness with different compounds would share the same elastic modulus?

There are secrets in rubbercompounding about how to improve the mechanical properties. Hardness and modulus are only two aspects in general.
Try ask this deep phenomenon about hardness and modulus (static and dynamic) to the rubber experts at

Thoughts?

I would think that if you were to thoroughly search the work on this area, that some fairly good correlations between shore hardness and bulk modulsus, for example, within sub-groups of rubbers, that have well defined levels of crosslinking, branching, DP, low crystallinity, and so on, could be found.
try scirus.com for a search engine and good luck!

It gives you an idea of how complex it can be

The gist of the discussion is that the relation between shoreA and modulus properties is only approximate though valid in the range ShoreA 30-60
