abaqus plastic data

[masoud1989]

Hello all

I want to model an blank in abaqus and the material is pure aluminum (A1100-O) with E = 70,000MPa, ρ = 2700 kg/m3,ν = 0.3, ¯σ = 180¯ε0.2 MPa and also i know "The strain hardening is described using individual points on the flow stress versus plastic strain curve, with an initial yield stress of 100 MPa and a maximum flow stress of 207 MPa."
i used elastic and density data but how can i use plastic specification...
i need to add plastic material in property module but i dont know how to use the above data to fill plastic data table in abaqus?

Best Regards

Please Read 23.1.1 in Abaqus user manual, specifically stress and strain measure. You will see how plastic strain is calculated from the true stress-strain curve.
