Hi All

I would like to know , how can I extract the equation of flow curve based on the stress strain graph ( scanned ) that I have , using the formulations of Hensel spittel or GMT ?

RE: Hensel spittel or GMT graph from steel stress strain curve

You convert the scanned stress/strain curve into a true stress/strain curve. You can find this out by searching.
