Hi,
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
