In particular, the Young modulus is different, but I also have two different stress-strain curves, one for tension and one for compression.<\/p>\n<p>I heard that the cast iron material model may be useful, but I saw that there are two cast iron model (one in GRANTA database and one in general materials) so I don&#8217;t know which to use, and also I used the isotropic multilinear hardening to input my tensile stress-strain curve but I don&#8217;t know where to put the compressive stress-strain curve.&nbsp;<\/p>\n<p>Do you know how to do it?
