MultiLinear Material

[ssami]

Hi everyone,

I have a question about the MultiLinear Material. According to the following link, in the unloading step, the value of stress for the forth node is shown 2f1, while in the explanation of the command, we can assign any value as stress for the forth node, namely f4. I am confusing which should be assigned?

You can assign any value. 2f1, 2f2, etc. in the image are used to show the unloading rules.
