Calculating Young's Modulus from this Stress/Strain Graph

  • #26
Thank you.

They are quite close.133MPa, 152MPa, 160MPa.

Shall i make the Toe smaller on some to get closer?

How can i make them closer?

You want to go further into the region where the data curves and was caused by experimental error? The definition of Young's modulus requires a linear regime.

No. You've been doing it right. Why are you trying to change things? Your black line to fits well with the coloured lines. You are done. There is nothing more to discuss here.
