Pinching4 Material

[MRG]

Hi
i want to model Steel Material with deterioration in my project . Can i use from Pinching4 Material to do it ?
i know parameters is relevant to Steel for example Fy Ey Fu Eu but i dont know other parameters and i dont need to consider those.
Please help me
thanks

I would suggest that you use one of the Steel01 or Steel02 materials. As is implied in their name, they work well with steel. You can use any material really, provided that they are set up correctly and implemented well in a fiber section, but the Pinching4 material inputs specific points and makes it well suited for an idealized force-displacement curve of some structural member (such as the P-M curve of a column that was previously tested).

My two cents.

dear fbeckwit
thank u for answering and appreciate for ur concern.
but now the problem is about these parameters,how can we get them and t find;
i think perhaps her or his question is about modeling of e.g: shear-tab connection
You are totally sober pronouncements my friend.
