Note: i simulate a concrete model in ls dyna but it was too rigid now i want to check the stress and strain curve but i don't know from where i can check it.
If you have any reference that shows , how to model a concrete that can represent real behavior of concrete, it will be very helpful for me
thank you in advance

Dear Safiullah Olfaty,
If you want to define a stress-strain curve of the material model in Ls-Dyna you should use following card *DEFINE_CURVE in Ls-Dyna and then use this curve's LCSS ID in your material card.
You can find more details in the following web site.

if you already have the cordinates defining the curve, you can load the xydata in .csv format.
