Reply To: Tensile test of AL 2024 T4 to calculate ultimate and yield stress

[Desi Gustiani]

Hello Mr.Peter

This is my eksperiment Tensile test Result. 

I took this graph data using Graph Grabber software, and I created a Stress and Strain graph.

This is my Engineering Stress and Engineering Strain.

I have convert From Engineering data to True Stress and Strain with this Vormula [From Ansys course]:

I have Result Engineering vs True Stress and Strain data like this:

Are my steps correct sir? What can I do for next step ? 

Thank you very much Mr Peter, I appreciate your help. Thank you again.
