Young's Modulus from DMA Data?

[mta02hm]

Is it possible to determine a value for Young's modulus from a material's storage modulus?

I have ran a number of tests using DMA in compression mode and have the data but I'm not should which point I should take as Young's modulus.

Would it be the point of inflection of the curve for a plot of Temperature versus storage modulus E'?

Thanx

As I understand it E´ is the elastic modulus and that corresponds more or less to the Young's modulus. Bear in mind that the Young's modulus is normally measured in tensile tests whereas DMTA measures the flexural modulus and the two values will usually be similar but not identical. (Bear in mind I am not a DMTA expert)

DMTA plots modulus versus temperature. The change in slope or "slope intercept" is one method used to measure glass transition(Tg). Storage modulus should be close to Youngs modulus but these numbers will change with test method. DTMA is not the method used to define youngs modulus and that is why it is called storage modulus instead.
