engineering stress-strain --> true stress-strain?
(OP)
Hi experts,
I am wondering if I can interpret engineering stress-strain data to get true stress-strain curve? It seems possible but I haven't got everything clear in my head. Wondering if anyone can educate me a little or point me to any available standard or practice?
I am not looking for a full true stress strain curve, a bilinear curve is fine - meaning two linear sections with only one yield point and one frature point. For steel or metal. Assume I have ys,uts, e and RA.
Thanks,
Salmon2

Happy holidays to everyone. I don't have time to be here a lot, but I think this is the best engineering forum. Hats off to all the experts.

My problem is to design a tool --> I wrote a material Spec
for it where I can only define minimum ys, uts, e, RA in a tranditional way --> then I want to run some FE stress analysis to verify if it will work --> FEA asks for true stress strain curve to get more reliable results (I do have several localized high stress beyond yield point). So I need to translate my material Spec to a true stress strain curve if possible.
