Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I know the following properties for steel,

Tensile Strength = 135000 psi

Yield Strength = 130000 psi

Elongation in 2 inches = 16% minimum

Reduction in Area = 50% minimum

Hardness (Rockwell C) = 29 - 34Rc

So from above properties I need to calculate the Elastic modulus & Poisson's ratio. This is how I went about it,

1. Calculate strain = change in length/original length = 2.32-2/2 = .16

2. Elastic modulus, E = stress/strain = 135000/.16 = 843750 psi

3. Poissons ratio = lateral strain/axial strain = .16/.5 = .32

Is the above procedure correct? Any help would be appreciated.

Thanks,

Mike
