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

I am trying to generate tabular stress-strain data from the data given in this table for a grade of aluminium,

The elastic region is simple but I don't understand how to use the 'strain hardening exponent' to generate stress-strain data for the plastic region. From what I understand it should follow this equation,

σ = Kε^{n}

where n is the strain hardening exponent

and K is the strength coefficient which is defined as " the extrapolated value of true stress at a true strain of 1.00."

Should I not have been given this value of K in order to plot the data or is there another way to generate the data based on the information given in that table?

Any help would be greatly appreciated!
