Material Properties

(OP)
Hi,
I'm using Autoform for FEA on forming sheet metal parts. My problem is that to accurately produce results in the software, I need to specify information regarding the material. I have all of the material specifications including composition, yield and tensile strengths and r/n values. I am trying to create the material for 436L stainless steel. Please find attached my material properties and a menu from Autoform that I need to add the information to. I'm not a metalurgist so I'm not sure what all the symbols meen. Unfortuanately the only way for me to obtain correct R0, r45 and R90 values is to test a material sample. But at this point I'm only working on this analysis from a feasability standpoint. If anyone could offer me some insight on what to fill in the menu from the properties, it would be greatly appreciated.
Thanks,
Rob

You forgot to add the "menu from Autoform that I need to add the information to."

RE: Material Properties

How about using average strain ratio, 1.3 for this case, for all three directions? This seems a fairly good start to me on the condition of no access to real testing and still including thinning effect, non-unity strain ratio.

RE: Material Properties

Try to be a bit more specific in the title.
