I'm analysing a simple truss structure in Abaqus, comparing the results from linear elastic, elastic perfect plastic and elastic linear hardening assumptions.(adsbygoogle = window.adsbygoogle || []).push({});

When it comes to linear hardening I need to define in Abaqus the plastic region of the stress strain curve. I know the gradient E of both regions of the curve and the yield stress and strain. I need to input a value of yield stress and plastic strain in Abaqus' plastic material properties so I was going to do this by plotting the whole curve and at arbitrary values of post yield stress drop a line parallel to the elastic curve to find the plastic strain.

Is this a valid method and if not what should I do instead?

thanks
