I am trying to calculate youngs modulus of elasticity for results from a tensile test but can't seem to get a figure close to that of the common figure for the material
Material 0.1% carbon steel
Area = 20 x 10-6
Yield force = 6009N
Length increase at yield force = 0.537mm = 0.000537m
Original length = 25.6mm = 0.0256mE = σ/ε
E = (6006/20x10-6) / (0.000537/0.0256)
E = 14.32 x 109
Typical value = 207 x 109
Iv obviously went very wrong somewhere but i don't know where
Thanks
