Poisson and Modulus of Elasticity of Al 2024 T6

Poisson and Modulus of Elasticity of Al 2024 T6

Poisson and Modulus of Elasticity of Al 2024 T6

Hi

Nowhere near my reference books.  Anybody have Poissons and Modulus of Elasticity for Aluminium 2024 Bar diameter 35.5mm in the T6 condition close to hand.

Thanks

RE: Poisson and Modulus of Elasticity of Al 2024 T6

Per the Aluminum Association:
Typical Average Modulus of Elasticity: 10,600,000 psi
Note: the Compressive Modulus is typically about 2% greater than the Tension Modulus.
Note: the Aluminu Association draws a distinction between "Minimum" and "Typical" properties.  Typicals tend to be about 15% higher than Minimums.  Use Minimums for design.  Then again, I think this just refers to strengths, not modulii.  Oh well...

Per "Aluminum Structures" by Kissel and Ferry:
Poisson's ration: 0.33

Cheers for the info guys

RE: Poisson and Modulus of Elasticity of Al 2024 T6

I use modulus of elasticity for thermowell calculations.  The modulus of elasticity varies with temperature.  I will check to see if I have Aluminium 2024 on my spreadsheet but cannot get to it now.
