element truss

[Sangwook]

Hello, I'm trying to use the truss now.
Here, I have one simple questions.

In material tag, if the hysteretic material is applied, we can input the stress and strain (or force & deformation).
Then, in case of truss, which information either (stress and strain) or (force & deformation) can be used?

Thank you!

truss: stress-strain
zero-length: force-displacement
