Yield and Ultimate Strength

Hello, How can I add Yield and Ultimate strength? My material is isotropic so ı will use Mat1 but I didn't find yield strength section.

    If you're looking to add a non-linear material to your model you can use the MATS1 option on the MAT1 card. In order to include that material in a non-linear subcase you'll need to add a NLPARM card to the subcase.

    Thank you, but My material is Inconel 718 and linear. I want to add those properties for topology optimization and safety factor.

    I see, in that case you don't need to change anything with the material property itself. You can just add a design constraint to the topology optimization problem. You can add stress constraints by property or element sets using a DRESP1 static stress response. Or you can add a global stress response on the topology design variable.

    Here is a tutorial for the global topology stress constraint:

    You should look into attending one of the Optistruct for Optimization classes, we cover this in detail.

    How can I attend the classes ?
